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.

To do it: Start seated, then lean back, resting your weight on your forearms (bending your elbows behind your body, fingers facing forward). Extend both legs straight out in front of you. Bend your right knee into a ‘passé position’ by pointing your right foot and pressing the inside edge of your right foot along the inside of your left knee. Draw your abs in tight and lift your legs off the mat and towards the chest (maintaining passé position). Bring your right knee all the way up to the right side of your chest and then lower your legs (still in passé) back down, about two inches from the floor (or as low as you can). Repeat 8 times and then switch legs. Try to do 8 reps on each side, for up to 2 sets.
Building muscle and burning fat at the same time is the holy grail of bodybuilding but many people believe that it’s impossible. Here’s how it goes. Experienced bodybuilders first bulk then cut. Bulking is the period where they eat more calories than they burn (caloric surplus) in order to pack on muscle mass. Cutting is the period where they eat fewer calories than they burn (caloric deficit) in order to burn off the fat they inevitably gained during the bulk. The remaining muscle after bulking and cutting is their lean muscle gain.
Directions: Begin each of these workouts with a five-minute warmup, or go through the moves after you’ve done your usual cardio or strength training when you’re already warm. Each should also begin with 20 reps of what Fitzgerald calls “transverse pullbacks”—where you pull your navel toward your spine, as if bracing yourself against a sucker punch—as a way to activate the muscles for the work you’re about to ask of them. You’ll also need some dumbbells for some of these moves.
Here’s a how a standard HIIT routine goes: one minute of strenuous exercise followed by 30 seconds of rest, repeated four to six times. You can do it for anything: sprinting followed by walking; biking full-steam followed by a casual pace; butterfly strokes followed by a doggy paddle. Or, if you really want to turn up the heat on HIIT, try out The Single Best HIIT Workout For Turning Back the Clock.

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.
The reason: Classic ab moves like crunches and situps work the muscles that allow you to flex (that is, round) your lower spine. True core exercises, on the other hand, train the muscles that prevent your spine from rounding. They also allow you to transfer force from your lower body to your upper body (in a golf swing, for example), and vice versa.
To do it: Stand with your feet hip-width apart. Bend your knees slightly (or more if needed) and place both hands flat on the ground. Keeping your legs extended and your feet planted, walk your hands away from your body, as far past your shoulders as you can, until you are in a full plank position. Hold for one count at the furthest point, and then walk your hands back to your feet and slowly return to standing. That’s one rep. Repeat up to 10 times.
Bicycle: This exercise works your obliques as well as your rectus abdominis. Lie on your back, hips and knees bent at 90-degrees, chest curled over ribs, hands behind your head. Extend the left leg out while bringing the right knee in towards the chest and rotating the left shoulder toward the right knee. Keep the arm from crossing the face. Rotate from the trunk through the center to the other side without dropping your chest. Move in slow, controlled movements without shifting your hips.
I absolutely despise the idea of a ketogenic diet because that’s something most of us can’t subscribe to for life. There are other popular diets besides keto like paleo and atkins that also demonize carbs and tell you that they make you fat. In my opinion, more food in general (which will invariably have more carbs) makes you fat, not carbs. Carbs are the basic fuel your body needs to function.
Everyone has six pack abs. They’re there, whether you believe it or not. The problem is that not everyone’s body composition is such that their abs are actually visible. These muscles don’t need to be created – they need to be revealed. Remember our “strongman” example – powerful upper body, mighty arms, and a layer of soft flab around their midsection? Believe me, Mr. Strongman is packing some serious stomach muscles, but like on a lot of us, they’re hidden under layers of adipose tissue. That’s why they’re not visible.
To do it: Start with feet in a wide stance, knees bent, arms up on guard. Keeping your lower body still, quickly lean your upper body to the right, then come back through the center and lean to the left. Repeat lean back to the right. Next, lower your upper body, from the right around to the left side, making a half circle with your torso. Return to start position. That’s one rep. (Tip: it helps to keep a steady rhythm with this move, think—or say aloud—1, 2, 3, weave to help you keep your tempo). Repeat 10 times total, alternating starting on the right and left sides.
For building muscle; follow a simple training routine that focuses on compound movements. Compound movements for weightlifting are deadlift, squat, and presses. For bodyweight training, they are burpees, push-ups, bodyweight squats, and pull-ups. These exercises are enough to train 80% of the muscles in your body. Add a few supporting exercises for the remaining muscles and you have all the exercises you need to build a great physique.

My Cardio and Callisthenics circuits really helped me increase my stamina and perform like an athlete. Some of my favourite ones are Burpees, Crab Walk, Jumping Jacks, Jumping Squats, Kettle bell runs and in general, circuits variations that really push me to the limit. I followed an HIIT program on the treadmill where I would run for 2 minutes and walk for 1 for a total of 12 minutes. I used the preprogrammed interval training option on the elliptical and stepper machine. I also went to the park sometimes for my workouts. You’ll be surprised at how different and relatively harder it is to train in the open.
