"This exercise is so effective because it teaches you not to rely on your bigger muscle groups (like your thighs) and focuses on using your abdominals correctly in a controlled manner without using momentum. The use of the ball gives you natural feedback of your weaker side so that you can adjust and work on symmetry of your musculature, preventing future injuries."
Lie on your back, arms behind your head, like you’re in a crunch position, with legs raised and bent at a 90-degree angle. Kick your legs back and forth like you’re riding a bike. While you do that, alternatively twist the upper part of your torso in tandem with your legs. For maximum toning, do this for as long as you can take it. Once you master this move, you’ll never forget it—it’s just like riding a bike!
As easy as the models and athletes in our magazine make being lean and ripped look, we’ve got to be honest, it couldn’t be further from the truth. It’s hard, it takes time, and it demands an unwavering degree of discipline. In our on-going efforts to assist you in sculpting the body you’ve always wanted, we’ve laid out the gold rules to getting ripped.

"I have researched this move in my lab, and it is very effective at activating all of the abdominal muscles (the rectus abdominis, internal and external obliques, and the transverse abdominins), and yet the movement is very straightforward and does not require several steps or positions, says Michele Olson, PhD, professor of exercise science at Auburn University Montgomery.
Dinner (9.15PM) — Vegetables sautéed in different masalas with some tomato curry, paprika seasoning and curd. Add different sauces from time to time for extra flavour. I load up on veggies while trying to get as many different colours on the plate as I can. For me, these usually are Broccoli, Bell Peppers, Beet Root and Zucchini along with regular ones like Spinach, carrots and cucumber. For weight training days, you want to introduce some carbs into your dinner. Initially, I stuck to Sweet Potatoes and Brown Rice but now occasionally have Roti, Rice, Brown Bread and even Pasta. On cardio days, I would add a cube of cheese or some paneer.
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."
"My goals six years ago was to 'get abs' and I used to think cardio and crunches would get me there. But it wasn’t until I started lifting weights and varying my abdominal exercises that I started to see a major change. You don’t realize how much you use your core muscles in order to perform powerful rapid movements like deadlifts!" — Shante Franca, @shantefranca
