Many people assume that strength training and cardio need to be done exclusively to reap the benefits of each. I came across this 20 REP SQUAT and I'm out of breath just thinking about it! What is a 20 rep squat?? Load up the bar with your 10 rep max weight. Do 10 reps, but WAIT!! Once those 10 reps are done, don't put the bar back on the rack. Let it sit there on your back while you catch your breath. Now, go down and do another rep. Catch your breath again, but don't rack the weight. Do another rep. Continue doing reps without racking until you hit 20 reps! It's guaranteed to have you lying on the floor for an hour after your workout. SIGN ME UP!!
