You’re ready for a group run or HIIT class and before you’re two minutes into it, you’re stomach’s rumbling, cramping and swelling. There are many weird side effects of working out and gastrointestinal issues are definitely part of them—some of the more embarrassing ones at that. (You've surely heard that Chris Weidman admitted to nearly soiling himself in The Octagon at UFC 187.)
So if burpees make you burp and running, well, gives you the runs, heed to this advice from Marni Sumbal—a dietician who specializes in sport nutrition for triathletes and runners—on preventing the most common stomach issues during a workout. Sumbal herself is a 9x Ironman finisher, so it’s safe to say she’s had some experience battling belly bloat and indigestion during training or a race. With her easy diet and lifestyle hacks, you can be on your way to a happier stomach and an overall more enjoyable workout experience for years to come.
