Exercise: Doctor shares a change to how you drink water that can boost energy and performance during exercise

The wellness and fitness market is full of supplements promising health and performance benefits. One that has grown in popularity is electrolytes.

PhD neuroscientist and Phizz co-founder, Dr Paul Anastasiades, spoke exclusively to GB News to explain what these are and how they can be beneficial in both your fitness regime and in everyday life.


What are electrolytes?

Electrolytes are essential minerals that help the body rehydrate, making them an important tool when taken around exercise.

Dr Anastasiades said: “Electrolytes are essential minerals like sodium, potassium and magnesium. They are often associated with exercise due to their critical roles in nerve and muscle function and the fact that fluids and electrolytes are lost through sweat, impacting physical performance.

“Electrolytes are particularly important during exercise, as you lose them when you sweat, so taking electrolyte supplements can help improve both physical performance and recovery. But they aren’t just for athletes, they also matter on a day-to-day basis because hydration underpins your energy, focus and overall mood.

“What is less well known is that electrolytes also support 100s of different biological processes, including immune system function and energy metabolism.

“Importantly, we lose electrolytes throughout the day, not just during sweaty workouts, so we need to keep our electrolyte levels topped up daily to ensure our bodies function optimally.”

Indeed, a study published in MDPI looked at the effects of electrolyte supplements on the body during exercise. It compared electrolyte drinks to plain water and found that electrolyte intake better maintained hydration and physiological balance.

What’s more, the improved fluid retention helped support exercise capacity and recovery compared to drinking water alone, showing their value for endurance and sustained performance.

This is particularly relevant for those training at higher intensities or for longer durations, where sweat loss is greater and hydration needs increase.

Hydrating with electrolytes is not just important when exercising, however, as those who enjoy an active lifestyle could get more out of the supplement than they realise.

Dr Anastasiades continued: “Despite an ever-increasing focus on health and fitness, fast-paced, high-stress, and increasingly active lifestyles lead many people to suffer from tiredness, low energy and reduced focus. What many don’t know is that one of the main causes of these symptoms is dehydration.”

Even mild dehydration can affect Britons in a number of ways. This includes difficulties concentrating, weaker muscle contractions, earlier fatigue during exercise, and distorted hunger signals, among other drawbacks.

So how can you combat this? The doctor said: “Combatting dehydration is not just about how much water you drink, but how effectively your body uses it. That’s where electrolytes come in. Certain formulations – like Phizz – use the power of electrolytes to help your body absorb and retain fluids more efficiently.

“Electrolyte-based hydration formulas offer a powerful solution to dehydration. When sodium is paired with a small amount of glucose, it helps increase the speed and efficiency of water absorption in the body. This supports hydration during or immediately after exercise, while also making hydration more effective in everyday life.

“This is why electrolytes are increasingly becoming part of people’s daily routines. By harnessing the power of electrolytes, we can stave off dehydration to improve our energy and focus. Advanced formulas, such as Phizz, also include other vitamins and minerals to provide a great-tasting daily supplement to support overall wellbeing.”

When is the best time to exercise in the heat?

When is the best time to exercise in the heat?

The sun is a welcome addition to our exercise routines come summer – but the novelty of a sunny run or hike can quickly wear off as the temperature climbs. With heatwaves and record-breaking temperatures already this year, it’s important to know the best time to exercise in the heat for the weeks ahead.

Obviously, if you don’t like the heat and would rather be inside, then you can exercise in an air-conditioned gym or studio at any time of day. A good swimming workout is another way to stay cool. However, if you enjoy running, hiking, cycling, or a garden strength training workout, it makes sense to choose the coolest times of day. In the peak of the summer, this is before 10 am and after 5 pm, but the earlier (or later) you can go, the better.

Kylie Minogue, 58, shares how she stays fit without a strict exercise routine – ‘I don’t really work out’

Kylie Minogue, 58, shares how she stays fit without a strict exercise routine – ‘I don’t really work out’

Kylie Minogue has stayed active her whole life, but, refreshingly, she doesn’t follow a punishingly strict routine to stay fit.

‘I wish I was one of those women who do their exercises first thing in the morning, or run straight to the fitness studio as soon as they get up,’ she told Star Magazine. ‘But unfortunately, I’m just not that disciplined!’

Instead, the ‘I Should Be So Lucky’ singer partly relies on her hectic schedue to keep her moving. ‘I don’t really work out, but I’m constantly on the go,’ she told Express.

‘My guilty confession is that there isn’t [a routine]!…I think I stay in shape with an active (read, exhausting!) lifestyle,’ she continued on Reddit. ‘My fitness is really sporadic. I have to thank my mum for good genes.’

Kylie Minogue’s go-to exercises

Despite her self-professed low-key approach, the global multi-platinum recording artist incorporates several workout methods into her day, preferring mainly low-impact and moderate-intensity exercise.

‘I do Pilates,’ she continued to Star. But she’s careful to keep things balanced. ‘I don’t overdo it,’ she clarified.

‘I like to at the very least do 15 minutes on the Yoga Studio app. I know how to do it without the app but the tone of the woman’s voice and that it’s timed, it goes by so quickly,’ she told WSJ. ‘Then I feel like that’s done and I feel good.’

Often, her exercise of choice also depends on what equipment is available.

‘If there’s a treadmill nearby, I like to do that. We say in my family, “Minogues don’t run.” None of us run. But we like to walk, so that works for me,’ she added. ‘If I’m somewhere where there’s Pilates, I love that.’

Workouts that provide holistic physical and mental benefits are often a favourite.

‘I’ve also tried Gyrotonics; that was really fun,’ she continued, referring to the gymnastics-and-swimming-inspired movement system developed by Julia Horvath in the 80s. Designed to decompress the body, build strength and flexibility, and improve posture, it’s increasingly being adopted by Olympic athletes and celebrities alike.

‘I loved aerobics and I used to do Callanetics,’ she added to Express. Created by classical ballet-trained Callan Pinckney around 40 years ago, Callanetics uses ‘small, precise pulsing movements’ to ‘activate muscles’. I would travel everywhere with this home workout on a VHS tape and put it on in hotel rooms,’ Kylie revealed.

However, being the ‘Princess of Pop’ does mean that the physical demands are considerable, and often her endurance, coordination and overall fitness are put to the test when she’s on stage.

‘I would say my ultimate workout is being on tour. I’m never as fit as when I’m on tour, so I can’t wait to tour again. My body needs it.’


One of our most frequently asked questions here at Women’s Health? How to build muscle and burn fat at the same time. So, we asked superstar trainer Oyinda Okunowo exactly how to do it.

Alison Hammond lost 11st and transformed her health by quitting these 3 habits – here’s how

Alison Hammond lost 11st and transformed her health by quitting these 3 habits – here’s how

Exercise played a pivotal part in Alison Hammond, 51, losing 11 stone. The This Morning presenter hired personal trainer Ellis Gatfield five years ago, and while introducing regular strength training helped her hit her goal, there were a few fitness habits she was also required to quit.

Below, Gatfield shares exactly what she stopped doing, how doing so helped her lose weight and build muscle and her full weekly workout routine.

A quick caveat: sustainable weight loss isn’t driven by exercise or nutrition alone. Movement helps preserve muscle, support metabolic health and improve how your body uses energy, but what you eat still matters. The most effective approach combines smart training with nourishing, realistic nutrition habits you can maintain long term.

1. She stopped doing long treadmill sessions

Gatfield says: ‘She never particularly enjoyed traditional cardio, so instead of forcing long treadmill sessions, I focused on raising her heart rate through resistance training performed in a circuit format, using mainly compound movements. This allowed her to get the cardiovascular benefits while also building strength and shaping her body. The biggest mistake from her training before was believing that exercise had to mean long, boring cardio sessions to lose weight. That mindset made training feel like a chore rather than something to enjoy.’

2. She stopped forcing exercise she didn’t enjoy

Gatfield says: ‘Once we shifted to a style of training she genuinely liked, everything became easier. Training stopped feeling forced, consistency improved naturally, and results followed. Enjoyment is often the missing piece in successful weight loss and it’s something I prioritise with all my clients.

‘Strength training played a huge role in Alison’s weight loss because it allowed her to burn calories, build lean muscle, and improve her metabolism, without relying on long or exhausting cardio sessions. Resistance-based circuits kept her heart rate elevated while also improving strength and body composition which is key for long term fat loss.

‘Just as importantly, she genuinely enjoyed this style of training. She loved being able to come in, work hard for 30 minutes, feel accomplished, and get on with her day. That enjoyment made consistency easy, and consistency is where results come from.

‘With Alison, the priority was keeping training effective, enjoyable, and realistic around her schedule. Sessions were always kept to around 30 minutes, which meant they were easy to commit to and never felt overwhelming.’

3. She stopped skipping rest days

Gatfield says: ‘Rest was equally essential [to her results]. Scheduled recovery days helped regulate stress, reduce fatigue, and allow her body to adapt and improve. That balance between training and recovery meant she could show up strong, train with intent, and sustain results long term.

‘For most women, especially those new to resistance training, I’d recommend two-three sessions per week. The focus should always be on learning proper technique, moving well, and recovering properly. More isn’t always better – consistency and quality matter far more.’

Alison Hammond’s weekly workout schedule

According to Gatfield, a typical week in workouts for Alison included:

  • Monday: 30-minute resistance circuit
  • Tuesday: 30-minute boxing session
  • Wednesday: rest or low-intensity walk
  • Thursday: 30-minute kettlebell circuit
  • Friday: 30-minute boxing session
  • Saturday: rest or low-intensity walk
  • Sunday: rest
