5 Best Bodyweight Moves To Shrink Your Waist in 30 Days

Torch belly fat and sculpt lean muscle with these bodyweight moves (no crunches or gear needed).

Sculpting muscle and shrinking belly fat through bodyweight training can be a highly effective way to achieve your fitness goals. How so? According to Jaqueline Gavino, MPH, CHES, exercise physiologist at Pritikin Longevity Center, muscle is a “metabolically active tissue,” meaning it torches more calories at rest than fat. When you perform bodyweight workouts, you rev up your overall energy expenditure and help transition your body into fat-burning mode, even long after your sweat session ends. That’s why we rounded up the five best bodyweight exercises to shrink your waistline in just 30 days.

What makes these exercises more effective than traditional crunches or sit-ups?

“These movements train the body to move better in real life. They activate the deep core, glutes, and stabilizers, promoting posture and joint alignment,” Gavino explains. “That’s important because the more efficiently we move, the more likely we are to engage in spontaneous physical activity, what we call NEAT, or non-exercise activity thermogenesis. This includes all the movement you do outside the gym, like walking, standing, gardening, or cleaning. Over time, those calories burned from NEAT can significantly contribute to reducing abdominal fat.”
