Squat and Jump legs back, push up then pivot body into side plank position and lift top arm up with hands stretched out towards ceiling in straight line, return to pushup postion, jump feet in and jump up. Alternate sides for each rep when you go into side plank. 

Get into high plank (push up) position, then bring one leg in towards chest, bending knee and with foot on ground; this is your start position. Simultaneously jump the bent forward leg back and the back leg forward alternating and jumping legs back and forth while keeping torso of body as straight as possible while performing these movements. Each time a leg jumps forward counts as one rep.

Jump sideways across an imaginary border and land on the outside leg, then lift inner leg and kick towards the side you just jumped from as high as you can, bring leg down and behind you crossing standing leg and bend front knee into a lunge, like a curtsy, then bring leg from behind back up to standing and kick again out to side as before. This is one rep. Repeat the same movements on the opposite side (as in a mirror) and continue alternating sides for each rep

From standing, bring legs up with knees bent one at a time as high as you can. You can put hands out parallel to ground and try to hit hands with knees as you bring them up, alternating legs and doing this as quickly as you can. This exercise is like running on the spot, except that you are keeping back straight and driving knees up high with every rep.

From standing position, bend knees into squat and reach down touching fingers to sides of feet. Then with an explosive jump, come up into a jumping jack, jumping legs out wide while and bringing arms out at sides and above head, then jump feet back in close together, coming down into squat and touching sides of feet again. This is one rep.
