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.
If you're not up for crunching numbers every day, you can take a more generalized approach. “For some people, it’s knowing, ‘Typically I eat a whole sandwich,’” says Gagliardi. “Now, I’m going to eat half a sandwich at lunch and save the other half for my dinner and cut my calories in half." To get started, consider these 25 ways to cut 500 calories a day.
Work your core. When many people think of core strengthening, they think of stomach crunches. Crunches are helpful for building abdominal muscles, but contrary to popular belief, crunches won't do much to lose the layer of fat stored in your belly, and can actually cause significant damage to the spine. Instead, try a workout routine that strengthens your whole core, like yoga, or try abdominal presses and planking.
