It's more challenging than a normal plank where your hands are on the floor, because the BOSU tests your balance, says Sanford. "When your body tries to find control as your balance is challenged, your abs, obliques, and deep transverse abdominal muscles are activated," he says. Strengthening these core muscles also helps increase your metabolism, ultimately helping you to burn more calories and fat.
2. Beta-alanine: This one doesn’t directly burn fat, but it does help you work out harder and longer, which in turn lets you melt that extra layer. The non-essential amino acid converts to carnosine, which is one of the strongest buffers against your muscles getting fatigued. Because carnosine keeps your muscles from calling it quits, studies have found beta-alanine can help your performance during HIIT, increase strength, and even help you gain more muscle to then reap all those metabolism boosts.
6. Fast once a week: While regularly underfeeding your body completely messes with your hormone balance, there’s sufficient research to suggest that intermittent fasting (IF)—or going without any food for set intervals—can actually help your insulin sensitivity and burn more fat. Researchers at LSU, for example, found that when people fasted all day, every other day, their fat oxidation increased and they actually lost 4 percent of their body fat in just 22 days. There are a lot of ways to go about IF, from fasting for 12 to 16 hours every day, to going 24 hours once a week. (Learn more about it here.)
Drink cold water: Staying hydrated period is important to keep your systems sharp, but adding ice to your water can help give your fat-burning potential a boost. German researchers found that drinking six cups of cold water can raise your BMR—that’s your resting metabolism—by roughly 50 calories a day because your body has to work to heat the H2O to body temperature.
“Medicine ball slams are a dynamic, explosive, and highly metabolic exercise that does not simply target one muscle group,” explains Chris DiVecchio, trainer and founder of Premier Body & Mind. On the surface, the obliques, hamstrings, quads, biceps, and shoulders are the primary movers of this exercise. “But as time goes on and fatigue sets in, nearly every other muscle in the body, in one way or another, may become involved as a secondary mover which makes this a total gut blaster,” he adds. Doing side-to-side ball slams versus overhead slams incorporates more oblique ab work.
How to do burpees: Stand with your feet shoulder-distance apart and send your hips back as you lower your body toward the ground in a low squat. Then, place your hands right outside of your feet and hop your feet back, allowing your chest to touch the floor. Push your hands against the floor to lift your body up into a plank and then jump your feet just outside of your hands. With your weight in your heels, jump explosively into the air with your arms overhead.
