I am a big fan of daily exercise in some capacity. whether it be in the form of steady state cardio or high intensity strength training. I feel the body is meant to move and needs to exercised on a regular basis. Anyway here is a workout that I have been playing around with on my non lifting days.
at the local track - but it can be done anywhere.
jog a lap
push-ups ( not to failure or even close)
jog a lap
crunches ( not to failure)
jog a lap
body weight squats ( about a minutes worth)
jog a lap
stretch and cool down
for me this workouts out to about 15-25 minutes of activity and serves to get the "lead out" after a tough workout the day before. - Doug Scott, Strength Coach
