This is a full-body workout designed to be done with no rest between sets. Do the first 10-minute cycle, then start again and repeat the entire cycle. You’ll get your workout done in 20 minutes, which is the amount of time it takes to play one half of a game of Madden. Best of all, this regimen gives your muscles the jolt they might not get with your old exercise routine. You’ll be doing less and getting more.
