On hardwood or tiled floor, place feet on two sliders and assume a high plank position (hands under shoulders, soft bend in elbows, butt and core engaged). Pull feet in toward chest, bending knees until you’re in a bear plank, knees below hips, but still lifted off floor. Slowly push feet back to high plank. Continue to repeat. To make it easier, move one leg at a time.
Attention to workout rest and recovery, as well as nighttime sleep, is also critical to promote muscle growth and hormone balance. You may find much of your time is spent working out or meal prepping — your social life, hobbies and downtime will likely be compromised. Don't forget, you must also keep up these regimens not just to achieve a six-pack — but to keep one.
Lie face-up and place your lower legs on a Swiss ball. Extend your right arm overhead and bend your left arm at a 90-degree angle; then grasp the upper portion of your right arm so you form a cradle for your head. Flexing your toes and holding the ball in place by contracting your hamstrings, crunch forward to the finish position. In this position, increase the tension on your abs by attempting to pull the ball towards you with your hamstrings. Return to the start and exhale. Your rectus abdominus can flex only about 30 degrees (strictly), so when you perform this exercise it may not be necessary to lift your shoulders off the floor to achieve peak contraction. You can make the exercise more difficult by pulling harder with your hamstrings, maintaining peak contraction longer and by holding a weight in your free hand.
Bent-Elbow Plank: This exercise works the whole trunk, particularly the transversus abdominis. Start by lying on your belly and then lift yourself up onto your toes and forearms (elbows in line with shoulders) while contracting your abdominals and keeping your back neutral. Hold that position for five seconds, then rest and repeat. Ultimately, strive to hold the pose for 90 seconds without any rest -- for one set. If you're more experienced, you can also do this exercise on your hands and toes. (As a beginner, start on your hands and knees with a neutral spine and simply contract the abdominals on an exhale without moving your back.)
Breakfast (9.30AM) — If you workout in the evening, nothing (IF). If you workout in the morning and it’s your cardio day, still nothing. On weight training days, 1 serving of Steel Cut Oats (why they’re better than regular oats) and skimmed milk, topped with some nuts and cinnamon powder. It’s imperative you replenish your muscle glycogen with some carbs post workout. I would usually cook 5–6 servings of oats on the weekend and store them in the refrigerator, using them through the week.
Creatine works twofold. It helps your muscles retain water, which means they’ll really pop, and it gives you long-lasting energy, which means you can make it through a grueling core workout, no problem. And taking it is effortless: just drop a scoop into your water bottle next time you head to the gym. (Best Life recommends the fruit punch flavor. It’s far and away the smoothest.)

"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
