For our purposes here, high-intensity cardio falls between about 80 to 90 percent of your maximum heart rate (MHR) or, if you're not using heart rate zones, about a 6 to 8 on a 10-point perceived exertion scale. What this translates to is exercise at a level that feels challenging and leaves you too breathless to talk in complete sentences. But you're not going all out, as in sprinting as fast as you can. There's no doubt that some high-intensity training work can be helpful for weight loss as well as improving endurance and aerobic capacity.
To avoid feeling hungry after a workout, eat a snack with at least 12 grams of protein before exercising, says Dr. Cheskin. And if you’re still hungry afterward? First, check in with yourself and make sure it’s actual hunger and not dehydration, says Dr. Cheskin. Then, eat a protein-rich snack that also includes some carbs, like a protein bar with whole grains.
Lose fat with high-intensity interval training (HIIT). If you're trying to lose weight fast, HIIT training can super-charge your metabolism for upwards of 24 hours after exercising. This means your body will continue burning calories long after you've ended your workout. HIIT burns more calories in less time than steady-state cardio. In one study, researchers looked at two groups, one running for 30 to 60 minutes three times per week, the other doing four to six 30-second treadmill sprints, resting for four to six minutes between each sprint. After six weeks, it was found that the group doing HIIT training lost more weight.
“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.
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.
Getting your Om on won’t burn as many calories as a hilly run or lifting weights, but it can help build muscle and improve your endurance, which are all crucial for boosting your metabolism. Some of the highest calorie-blasting yoga poses include plank, chair, Chaturanga, and wheel. New to yoga and aren't sure where to start?
