Why it made the list: There are many reasons to like leg raise variations, but one is their scalability. You can start doing bent knee raises in the Roman chair or ab straps to focus on the lower core, work up to straight leg raises, and then move to a hanging bar. By the time you can do full straight-leg toes-to-bar raises, your entire core will have strength for days.
Do it: Lay face up on the floor with arms straight above your shoulders. To start, bring your knees directly over your hips and bend at the knee so that your calf forms a 90-degree angle with your thigh. Next, simultaneously lower your left arm above your head while straightening your right leg and sending it towards the floor. Pause, return to the starting position, and then repeat on the opposite side. Do 14 alternating reps to complete one set.
To do it: Lie down with a small ball (a small pillow will also work if you don’t have a ball) under your heels, both arms extended over your head, palms facing towards each other. Inhale to prepare as you lift your head, neck, and shoulders off the floor and then exhale as you continue to roll up by drawing in your abdominals, reaching up and over towards the feet. Keep your abdominals contracted, with your spine rounded in a ‘C’ curve, and then inhale to prepare and exhale as you roll down through each vertebra in a controlled movement, keeping your heels pressed evenly into the ball the entire way up and down. Do 15 reps as controlled and precise as you can.
The recipe for six-pack abs isn’t all that complicated: Crank out an abs workout, eat a nutrient-rich diet, and consume fewer late-night pizzas in a single sitting. The undisputed holy grail of men’s fitness is good for more than just an extra boost of confidence whenever you have cause to peel off your shirt, too. “The best way to avoid injury, whether in the gym, at home, or at the workplace, is by building a strong core,” says Edwin Wealth, NASM-CPT and trainer at Equinox. Want to do yoga better? Run faster? Squat heavier? Carry the groceries without wincing? It all begins with your core.
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.
Why it made the list: It turns out the ball is good for more than just sitting and waiting for your partner to finish his set! A research team from California State, Sacramento demonstrated that the pike movement is one of the most effective total-ab workouts. It topped their EMG list for upper abs, lower abs, and obliques. This movement may be the heavy hitter that's been missing from your daily routine. While not exactly the same, the pike can also be done using a TRX system with similar results expected.
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.
