Training antagonistic (opposing) muscles groups has been touted for years as one of the more efficient, effective ways to work out. It provides great blood flow and “pump” to the target muscle groups, enhancing growth and recovery. One of the more unrecognized benefits is that it can be used to train functionally in an extremely effective manner.
To some degree, many antagonistic muscle groups work almost in unison, with one flexing or working while the other stretches or relaxes. Consider a bicep curl: As you lift the weight, the biceps get tight, obviously, and at the same time, the triceps get a break; switch up this movement, to, say, a triceps pushdown, and the biceps become elongated and nearly taken out of the equation, only returning to flexion at the very top of the triceps movement.
To apply this to a big-muscle group, consider a push-pull workout, which targets the chest, shoulders and back functionally when done properly. Supersets are a great way to get through these workouts, as multiple muscle groups can mean prolonged exercise sessions. The chest, triceps, shoulders and core all benefit from pushing movements; pulling movements strengthen the biceps, core, back and parts of the shoulder as well.
3 Supersets: 12 DB Bench Press/12 Bent-Over DB Rows. If you’re feeling like you really want to move, you can use the exact same dumbbells for both movements, never setting them down.
3 Supersets: 12 Incline BB Bench Press/12 Wide-Grip Pull-Ups. If you can’t do 12 pull-ups, either use an assisted pull-up machine (if you can’t do even 6-8) or go to failure.
3 Supersets: 10 Plyometric Push-Ups/12 Medicine Ball Slams. If you don’t have access to medicine balls (or the gym doesn’t like you slamming them into the ground), you can sub in Wide-Grip Standing Cable Pushdowns.
3 Supersets: 10 DB Flys/10 Inverted Rows. Perform your inverted rows on a Smith machine by lowering the bar, then simply pull yourself up, belly up and body parallel to the ground.
