Here is a great, leg-day routine. Perfect for when you have limited time but you want a killer workout. I threw a few abs in just for fun.
Complete the following for 30 minutes with 1-minute rest in between rounds:
10 Weighted Squats
10 Step-ups each leg, with weights
10 Stiff-legged dead lifts, with weights
10 Jump squats
100 Sit ups
10×10 Decline crunch with ball
