Wall Balls

150 Wall Balls using 25 lbs. Day 3 and I'm just getting over the "crippling" feeling I've felt like the past 3 days. The workout called for 20 lbs. Last time I did it I used 15 lbs because we don't have 20 lb weights (we are working at getting a full set of dumbbells but they are expensive). This time I thought I'd push myself and did 25 lbs. Ouch!
