Sit on the floor, knees bent, feet flat in front of you. Lean back and lift your feet, straightening your legs into a V position. Hold this position for 30 seconds.


On your back, with knees bent and hands behind your head, raise your head and feet off the floor and begin cycling your legs. Bring opposite elbow to knee as you go. Do 60 seconds, rest 20 seconds, and go again.

Russian Twist.

Seated, lean back so your torso is at a 45-degree angle with the floor, keeping your feet grounded and legs bent. Rotate your body left, then back through the center, and to the right. Perform 30 on each side.


Lie face-down, torso propped up on your elbows. Raise your body to forms one long line from shoulders to feet. Aim to hold 90 seconds — or until failure.

Hanging Leg Raises

Hang from a bar. Engage your core and raise both legs straight in front of you. Repeat until failure.

Flutter Kick

Lie on your back, heels about 6 inches off the ground. Hands by your sides, scissor your legs up and down for 20 seconds, rest 10, then do 20 seconds more.

Leg Drop.

Lie on your back on the floor, legs straight up in the air. Lower your straight legs to just above the floor, then raise them. Do 10 reps, rest 10 seconds, then do another 10 reps.


In a plank, slowly pull one leg in to bring your knee to your chest, then return your foot. Switch legs. Repeat. Do 30 on each side.


The cousin of full sit-ups, crunches involve lying on your back, feet either flat on the floor or elevated in the air with knees bent. Perform small contractions of your abdominal muscles to raise and lower your torso a few inches. Aim for 100 crunches.
