Muscles exert higher EMG tension when they are contracting eccentrically (lowering the resistance) versus raising it; but the problem with most exercises is that the amount of weight you can lower is limited by how much you can lift positively (concentric work). This exercise compensates for the problem by changing the leverage during the lowering (eccentric) phase of the exercise.
Protein — The building block of muscle and that mystical term for most beginners. If you don’t consume enough protein while staying in a caloric deficit, you’re going to lose a lot of muscle mass along with that fat, drastically reducing your TDEE. More muscle means you can get away with eating more because muscles store glycogen which in turn give you energy. Also, more muscle makes you look more fab. Ever wondered why those people who go on a crash diet and lose a lot of weight gain it all back when they return to their old eating habits? Now you know!
"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
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.
We all want a solid core for different reasons: sports performance, pain prevention, that finish line photo—but strengthening your midsection is particularly important for runners. That’s because your core is the stabilizing center of your body (it keeps you standing, least of all sprinting), and it can make or break your speed goals, prevent (or contribute to!) an injury, and yes, make you feel pretty badass in a sports bra.
In addition to this, you must also avoid sugary products (pastry, candy bars, coke etc), as sugar has a series of negative effects on your health, and it also contributes to belly fat which is the most difficult to get rid of!  Of course you will be tempted now and again so have a cheat day once a week when you can have your favourite “bad foods” but don’t go too crazy!
When it comes to working the core, many people focus on abdominal muscles, and neglect their obliques (or what you may know as “side abs”). But, says Barrett, these clandestine muscles are just as important: they “keep everything tucked in.” To get a good oblique workout in, head to the pulley machine and start doing some Paloff presses. If you don’t know how to perform the exercise, read our comprehensive guide on mastering the move.
Leg day, arms day, chest-and-shoulders day. You already break up your regular workouts by muscle group; steal a page out of Alicia Vikander’s ab-shredding book and do the same to your core. To get ripped for Tomb Raider, Vikander broke her core workouts into three days: isometric (endurance moves, like planks); strength (sit-ups, hanging leg raises); and oblique-specific (told you so).

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.
