TikTok fitness content may cause body image issues, study says

“Fitspiration” content on TikTok reinforces harmful body ideals, spreads health misinformation, and contributes to the oversexualization of women, according to a recent Australian study.

The study defined fitspiration content as “images and videos that aim to inspire individuals to live an active and healthy lifestyle through diet and exercise.”

Scientists at Flinders University expressed concerns that it could contribute towards body dissatisfaction, excessive dieting and the glorification of eating disorders among TikTok’s largely teenage user-base.

“Our study highlights concern about the triggering and misleading information portrayed by unqualified influencers and that we need far greater scrutiny of the TikTok fitness community,” said lead author Samantha Pryde in a statement.

“TikTok fitspiration videos often promote an idealized view of body types and there is concern that this is causing negative body image issues especially in young women.”

Scientists at Flinders University analyzed 200 TikTok fitspiration videos using popular hashtags such as fitness, fitspo, gymtok and fittok.

The vast majority were posted by fitness influencers without relevant qualifications, and as many as 60 percent were found to contain incorrect or harmful information related to diet, health and fitness, the study found.

“Worryingly, we found that the vast majority of influencers behind the content lacked credible health and fitness qualifications, underscoring a pervasive issue where influencer popularity overshadows the accuracy and safety of the information they provide,” said social scientist Professor Eva Kemps, a co-author of the study, in a statement.

Associate professor Ivanka Prichard, also a co-author and an expert in body image, exercise and health psychology, added: “Our study illustrates the need for more research and enhanced regulation regarding advertising by influencers on social media.

“We need more collaboration with public-health organizations, so that fitness influencers are encouraged to share evidence-based information that promotes healthy, realistic expectations for body image and fitness.”

The team discovered that more than half—55.7 percent—of the content they analyzed featuring women involved sexualization or objectification, while 20 percent involved body shaming and 8.6 percent promoted disordered eating behaviors.

“Alarmingly, we found that the majority of the videos perpetuated negative messages, including sexualization, body shaming and excessive dieting,” said Pryde.

Fitspiration content featured solely women more than solely men—78 and 10 percent of the videos respectively—and content featuring women promoted appearance-related reasons for exercise more frequently than videos featuring men.

The scientists found that women’s body parts were more often objectified too, especially the thighs and buttocks, and that the ideal female body type tended to be thin and fit.

“TikTok fitspiration videos often promote an idealized view of body types and there is concern that this is causing negative body image issues especially in young women,” said Pryde.

“The content typically showcased and promoted an ideal ‘thin’ body type, indicating that thinness is still a key driver of body issues for women that can negatively impact their physical and mental health.”

However, men were objectified in these videos as well, likely to be portrayed as muscled. Videos of men tended to feature bodies with obscured, blurred or cropped-out faces, and featured groups of men—whereas women were more likely to be featured solo.

“This evolving objectification raises concerns about the impact of fitspiration on male body image as well, with increasing evidence suggesting that male viewers are similarly affected by idealized imagery,” said Kemps

The study authors said that this likely reflected gendered workout habits, with the gym seen as a social, competitive space among men, and exercise a solo endeavor for women.

“In a world increasingly influenced by digital media, monitoring the impact of fitspiration content remains crucial in promoting and protecting healthier body image narratives, and fostering supportive fitness cultures,” said Prichard.

Recovery Tools are a Wellness Non-Negotiable—8 Expert-Approved Essentials

It’s not only athletes that require some serious recovery after exercising—even shorter runs or studio classes can leave anyone with sore muscles that require TLC. Taking care of your body post-workout is just as important as how you prepare for the exercise itself, so having recovery tools that really work on hand is essential.

“The recovery tool market has seen a massive surge over recent years, and it likely will continue to grow. However, it’s important to remember that the academic evidence shows that a hierarchy still exists for recovery, sleep, nutrition and training load. These are then complemented by the tools,” highlights Arj Thiruchelvam, running coach and Performance Physique founder with over 20 years’ experience in elite sport under his belt.

Power up! Could force be the secret to supercharging your fitness?

Power up! Could force be the secret to supercharging your fitness?

Chasing after your dog, catching yourself before you fall, jumping over a big puddle. These activities all have something in common, and it’s not just that they’re the makings of a very bad day. They rely on power: the ability to generate force quickly. It’s an often overlooked part of the fitness menu that experts think deserves more attention.

Mobility, cardio and strength all help us stay active and healthy as we get older. Strength training in particular has boomed in recent years, as the importance of building muscle mass to keep us strong, protect our bones and help us stay mobile as we age becomes more widely recognised. But when it comes to activities such as pushing yourself up from a chair or moving your arms quickly to break a fall, the size of your muscles will only get you so far. You also need power.

Imagine throwing a shot put, says Oly Perkin, a researcher at the University of Bath specialising in exercise to improve health at all stages of life. “You might have the strength to move the shot put from a start position to the top position. That’s largely down to your muscle mass. But to do that super quickly, to produce the force needed to propel the shot into the air, a different kind of strength is required.”

That explosive force depends on how quickly the nervous system can activate those muscles – the speed and efficiency of the brain-muscle connection.

For younger, active people, improving power can help prevent injuries. It can also help people who lift weights break through a training plateau. Where power training may matter most, though, is in reducing some of the effects of ageing.

“As you get older your muscles shrink and that is inescapable, irrespective of how active you are,” Perkin says. “If you make sure that the neural element is maintained alongside the muscle, your ability to maintain physical function across your life is much better. Even if you inevitably lose muscle mass, there’s good evidence that you can make better use of the muscle you have.”

The challenge is that power tends to decline faster than strength. After the age of 40 people typically lose about 1-2% of muscle mass each year. Alarmingly, muscle power can decline earlier and much more rapidly. The encouraging news is that power can be trained.

You build muscle by moving heavy weights a few times a week and increasing the load as it becomes manageable. The tension that the exercise places on the muscle fibres triggers a remodelling process that leaves the muscles better able to handle the stress next time.

Power is built differently. Instead of lifting heavy weights you move lighter weights, or your own body weight, but as quickly as possible. This could mean plyometric exercises such as box jumps. It could also include weighted movements such as throwing and catching a medicine ball, weighted jumps, snatches (where you grab a dumbbell from the ground and pull it towards the ceiling) and kettle bell swings. Weight-wise, you want something at about a six-out-of-10 difficulty level.

For older or less mobile people, power training can start with very simple movements. Try wall push-offs: lean diagonally with your hands against a wall, arms bent, and push yourself away at speed.

Perkin adds that, although everyone can benefit from training power, it may be especially valuable for older adults who have already experienced a significant decline in muscle mass. When muscle loss reaches the point of immobility, rebuilding it becomes very difficult. But improving the nervous system’s ability to activate the muscle that remains is still possible. “Growing muscle when you’re old is hard. There are physiological limits,” he says. “But for most older adults the capacity to improve neural function is still quite good. Within three or four weeks you can start to see improvements in key markers.”

If you’re thinking of stepping into your power, Perkin, alongside Alex Dinsdale, senior lecturer in sport and exercise biomechanics at Leeds Beckett University, and Leigh Breen, a leading expert in the field of skeletal muscle physiology and metabolism from the University of Leicester, share their tips.

Find your benchmark

A good way to test whether you could benefit from power training is if you can hold a squat but can’t squat jump more than a couple of inches off the ground, says Perkin. But jumps are also useful for measuring progress for those who have already built some power. Dinsdale says that when he works with athletes they regularly test power by incorporating jumps into sessions and measuring the heights or distances achieved. This may include static jumps on to boxes or broad jumps where you jump forward from a standing start.

For older or less active adults, the sit-to-stand test is useful. Sit in a chair with no armrests, cross your arms over your chest with your hands on your shoulders and keep your feet flat on the floor. How many times can you move from sitting to standing in 30 seconds? Over-65s should aim for at least 11 repetitions.

Perkin recommends using the same exercise to improve your power by doing three sets of 12 to 15 sit-to-stands while wearing a weighted vest.

Train with a goal in mind

“Obviously the main goal should be good general health and longevity,” says Breen. “But beyond that, everybody has something specific they want to achieve.” It’s useful to keep that end goal in mind as a motivator, as you’re less likely to see visible results than you are with strength training. It doesn’t have to involve training for a marathon or doing a Hyrox competition. It could simply mean restoring a functional ability that has been lost, such as being able to throw the bin bags into the outside bin or chasing the grandchildren around. “I think it’s always important to keep the purpose in mind when we undertake a training regime,” says Breen.

Get the timing right

All our experts say power training should come after you’ve warmed up, but early in your workout. It’s harder to develop neuromuscular speed when your muscles are fatigued; and it’s easier to injure yourself doing rapid movements when you’re exhausted.

Keep sessions short, adds Dinsdale. The focus is on how quickly you can move something, which means working at your maximum possible speed. You can only sustain that for short bursts. If you’re using weights, choose a light or moderate load and move it five or six times. Do three sets of three exercises, resting between them. You’ll want two to five minutes between sets so your systems can recover fully.

You don’t need a separate session

Doing a couple of power exercises a few times a week is more effective than doing many of them once a week. A simple approach is to add a 10-minute power block to the beginning of any regular strength workout. That could be three rounds of 10 kettlebell swings (which help with the posterior power chain), medicine ball throws and slams (to improve upper body speed) and weighted squat jumps (lower body).

Runs can also be tweaked to include power work. “You could do short periods of sprinting, maybe five or 10 strides as quickly as you can,” says Perkin. “Or stop briefly and do a few vertical jumps.”For those who aren’t confident with weights or jumping, Breen recommends doing medicine ball throws while seated (they’re still effective).

Take it steady

On first trying power training, it’s tempting to reach for heavier weights than necessary, says Dinsdale. Instead start lighter. “Use about 50 to 60% of whatever your maximum is for that movement [your maximum is the weight you can only lift once], and then build up,” he says. He adds that there’s very little benefit to going very heavy with these kinds of exercises if your focus is building mind-muscle connection.

Because you’re moving quickly, safety matters. As well as lighter weights, it’s important to focus on maintaining good form. If you’re unsure, Dinsdale recommends working with a trainer or taking gym classes while you build confidence.

Don’t be fooled by the name of workouts

Confusingly, powerlifting – lifting heavy weights without a time limit – doesn’t actually train power. Olympic weightlifting – with moves like the clean-and-jerk, where a barbell must be moved quickly off the floor and then into the air – does. For most people, power walking doesn’t train power either.

Use power to break through a plateau

Power training can also help people who feel stuck in their strength training. “When you lift weights you can reach a plateau where it becomes difficult to increase muscle size further,” says Perkin.

Adding lighter power work for a few weeks can sometimes unlock further gains. It forces your body to adapt by increasing the efficiency of the neuromuscular system. This enhances your ability to move heavy weights when you go back to them. “Then you have the opportunity to grow more muscle again. There’s a crossover effect,” adds Perkin.

Try a sport

If gyms feel intimidating and you’re right at the start of a power journey, playing sport can be another way to develop a beginner level of power. Activities such as tennis, padel, football or netball involve short bursts of acceleration that engage the mind-muscle connection, with the added social benefits. Contact sports, such as rugby and boxing, require explosive power too. The most important thing is finding a varied routine you enjoy.
