December is great for many things – socialising, scoffing, falling out with relatives – but sticking to a training schedule is not one of them.

Heading out the door on Christmas morning for a two-hour long run is likely to put anyone on the naughty list, while it takes a dedicated runner indeed to spend part of the festive period running loops of the track.

What the mere mortal needs is exercise “snacks”. These can be enjoyed/endured alongside the carb-based variety and snuck in to even the busiest Christmas schedule.

I love many different herbal teas just as much as I enjoy a good old-fashioned British cup of PG tips, Earl Grey, or Glengettie — a Welsh favorite from the rolling valleys where I was born. In an interesting study, researchers explored whether drinking green or matcha tea can improve sports performance and exercise recovery, and the results might have you reaching for a vibrant green drink. If you want to get straight to the results, the short answer is that drinking green and matcha tea can support hydration, body fat control, and exercise recovery. Still, it definitely won’t be a game-changer when it comes to your performance in the gym, on the court, or on the field.

Hydrating with tea

In a study published in Nutrition and Food Technology, researchers reviewed existing studies of athletes and active adults that focused solely on drinking tea — no pills or extracts. They revealed that green or matcha tea can help hydrate the body when consumed in normal amounts. Tea counts toward your daily water intake.

Antioxidants and recovery

The research highlighted how the widely-studied antioxidants in green and matcha tea can improve exercise recovery and help protect your cells from the stress associated with intense exercise. That said, the research shows that drinking tea won’t lead to faster or better strength gains, so it’s no silver bullet for helping you achieve your fitness goals. However, they also concluded that low-caffeine green tea could even improve sleep quality, which I would argue could potentially help you power through that workout if you’re getting better sleep the night before.

Linked to lower body fat

Interestingly, the study authors also concluded that drinking around two or three cups of green or matcha tea per day was associated with slightly lower body fat and improved body composition and fat burning. While the effects weren’t overly significant, they were noted in the research. Cup of tea, anyone?

Preparing for a Physical Marathon

Before the tour began, Swift recognized the physical challenge she was about to face. “I never would’ve believed you if you told me we were doing a three-and-a-half-hour show. Saying it is one thing, doing it is another,” she admitted in the Disney+ docuseries The End of an Era. For comparison, her longest previous show had lasted just two hours and 15 minutes.

To meet these demands, Swift began training six months ahead of her first rehearsal. Her daily treadmill sessions mirrored the tempo of the songs she would perform live, with faster tracks prompting running and slower songs calling for brisk walks or light jogging. “You just don’t want them to see you panting,” she explained to TIME.

Strength and Conditioning Regimen

While cardio built endurance, strength training ensured she could perform high-energy choreography without fatigue. Under the guidance of longtime trainer Kirk Myers, Swift tackled exercises such as battle ropes, medicine ball throws, assisted pull-ups, sledgehammer workouts, leg raises, and Russian twists. Myers described her as “the most resilient person I have ever met,” highlighting her ability to persevere through challenging workouts.
