HSS on Good Morning America’s Fit Myths series

Good Morning America presented a 'Fit Myths' series during the week of September 28, 2015 where each day they debunked another fitness myth. Four experts from Hospital for Special Surgery were featured in this 5-part series. Take a look!

Monday's Myth: Weightlifting

Good Morning America debunks a common fitness myth that weightlifting actually makes you become bulkier. Reporters suggest that weightlifting makes individuals more tone, rather than bulkier.

"In general it is very difficult to get bulky from lifting weights," said Dr. Riley Williams, sports medicine surgeon at HSS. "You really have to challenge yourself to see major muscle gains that way."

Tuesday's Myth: Is Your Workout As Intense As You Think?

Good Morning America visited the Tisch Sports Performance Center at HSS to test how many calories you actually burn during a workout as many people tend to overestimate this amount.

"It takes a long time to burn a lot of calories, and a very short time to eat those same amount of calories," said Polly de Mille, Exercise Physiologist at HSS. "You may go for a run and burn 500 calories and you can probably eat that in 30 seconds."

Correspondent Mara Schiavocampo and two additional volunteers participated in three workouts (running on a treadmill, a bike session and the 7-minute workout) while hooked up to our machine to measure calorie release. Watch to see if they correctly guessed how many calories they burned in their workouts.

Thursday's Myth: Hot Workouts

Good Morning America debunks a common fitness myth that hot workouts are better to help you get into shape and lose weight. Experts weigh in on hot yoga and exercising in the heat such as with trash bags and heavy sweatshirts.

"What you’re doing is you’re increasing your external core temperature and increasing your heart rate," said Michael Silverman, physical therapist at HSS. "Although it feels harder, you’re not actually burning more energy or more calories."

Friday's Myth: How To Fuel Your Workout

As the series concludes, Good Morning America discusses the right way to fuel your workout. Jason Machowsky, sports dietician at HSS, shares insight into the best foods before, during and after your workouts.

"You don’t want to start the workout starving or stuffed," said Jason. "If you go longer than 2 hours post-workout to eat, most people tend to get really hungry and that leads to being ravenous so they make poor food choices because they’re starving."
