To do the V-sit, start in a seated position on the floor, contract your abdominal muscles and core, and lift your legs up to a 45-degree angle as pictured. Reach your arms straight forward or reach up toward your shins as you are able. Maintain good core posture and a strong spine while you hold the position for several seconds. Rest and repeat several times. As you get stronger, hold the position longer.
Maintaining a high protein intake —Maintaining a super high protein intake is imperative to ensure your body has enough to preserve existing muscle, ideally build more and also prevent muscle breakdown for energy while in a caloric deficit. I stuck to around 0.8 to 1 gram of protein per pound of bodyweight to ensure I allowed my body to not only preserve but grow muscle as well. For me, this came around to 130–140gms of protein a day.
Let's come clean from the start: We're not here to sell you on the single "best ab exercise ever." Too many organizations and authors have tried that, and the profusion of "winners" out there can make it confusing—especially because the studies backing them are always limited in one way or another. A few years ago, it was the bicycle crunch. Then it was the traditional crunch. Then it was the pike, the plank, the roll-out... We could go on.
But there's science behind this buzzkill. The rectus abdominis — the muscle that makes the stomach look defined as hell — is typically covered by fat (because that's how humans are made) and isn't affected by things like crunches and planks. "You can work your abs all you want, but if you have a layer of fat over them, the 'pack' can’t be seen," Ball says. And FWIW, that's not a bad thing or something to feel bad about. "It’s very unrealistic for most people to have body fat percentages low enough to see the abs."
As they do, you should try to include at least one of the exercises described herein into your personal training program two times a week. These exercises can be made more difficult, but I seldom advise more than 10 – 20 slow reps on any of them. You should increase the resistance with these exercises rather than the reps; and if you’re working hard enough, you should only perform 2-3 sets per exercise. I would also suggest that you not perform any single exercise for more than three weeks in a row, since well-conditioned muscles adapt quickly to any exercise, and this adaptation must be minimized.
6. Seek guidance from experts. As with many health issues, getting assistance from experts can be enormously helpful. If you want to lose weight, particularly fat, seeking guidance from a registered dietitian or a nutritionist can be very beneficial, Herrington says. Similarly, if you want to build on weight loss to achieve more defined abs, consulting with a certified sports trainer can aid you in developing a workout regimen that will help you achieve your goals, Singer says.
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.
