Indoor no equipment workout

Since it is sub zero here and has been since Monday, I figured I would post a quick, equipment free workout.

begin with 20 calf raises, 20 knee raises, 20 forward kicks/side, 20 side kicks/side, 20 kicks to the back/side

25 jumping jacks
45 second plank on forearms
25 high knee runs/leg
40 second side plank, each side
25 running butt kicks/leg
45 second straight arm plank
20 jumping squats
20 bicycles (20 to each side)
15 push ups (as many as you can on toes before going to modified.  Always begin on toes!)
5 roll ups
20 jumping plies
10 tricep/pilates push ups (elbows graze rib cage throughout entire movement)

repeat 2-3 times.  minimal rest in between each exercise.  Remember to think about form (no knees going past the toes in any exercise, especially control your landing with jumping ones). Keep that belly button pulled in throughout all of exercises to protect low back.  Any questions let me know and let me know how it goes!
