Knee Strikes Start out in a pushup position, resting on your toes and elbows. Keeping your abs pulled in tight and your back straight, raise one leg up off the floor, bend your knee and bring your knee up as close as you can towards your shoulder, then return to start. Complete all reps on one side before moving to the other side.
Start out in a standing position. Jump your feet back and out from under you, land flat on the floor, bracing yourself with your arms. Jump your feet back to your hands, stand up and clap over your head.
Side Plank Lift – Lie on your left side with your legs straight and one foot resting on top of the other, one hand in front of your body for balance while propping your body on your elbow. Your elbow, hip and legs should be the only part touching the ground. Now lift your entire body off the floor and back down. Alternate which side you use with each interval.
Plank Jumps – Start out in a pushup position, resting on your toes and elbows with your feet together. Jump your feet out wide then back together, that is one rep.
Superman – Lie on your tummy, legs straight, with your hands outstretched on front of you, palms flat on the floor. Tense your abs and back and lift your upper body and your legs off the floor, as high as you can, then return to start. That is 1 rep.
