Regular cardiovascular exercise should be an essential part of your plan. I recommend you try and get in three to five cardio workouts per week. If you find you’re not losing as much fat as you’d like then shoot for five sessions a week. If your progress is good then you might be able to get away with just three sessions a week. Adjust appropriately based on your rate of progress.
But instead of just trying to perform as many reps as possible, slow down and really focus on the quality of the movement—especially the eccentric, or downward motion, of the exercise, he says. “The eccentric contraction is the most important phase when sculpting any muscle.” Plus, focusing on quality over quantity will help protect your back (some experts say crunches can be potentially troublesome for guys with back issues.)
“You will not make more muscle by trying this route,” says McComsey. When you do cardio you’re burning calories, but you’re not stimulating your muscles to grow as you would with weight training. “The more muscle you have, the more calories and fat you’ll be burning,” he says. McComsey recommends hitting the weight room three or four days per week, with one of those days being a circuit with a variety of exercises. If you need to do cardio, try one day of 20-minutes of fast-slow intervals.
To do it: Stand with your feet planted 3-4 feet apart, toes slightly turned out, hands on your hips. Lower into a plie by bending your knees out over your toes and lowering your hips directly underneath your shoulders. Then, as your straighten back up, slowly lift the right knee up towards the right shoulder. As you go back into the plie, slowly return the foot to the floor. Be sure to move at a very controlled pace to really engage the obliques the entire time—on the way up and on the way down. Do 10 repetitions on the right side, then another 10 repetitions on the left side for a total of 20.
