Up to this point, The Classic Iron Workout Program has primarily focused on traditional, big-rock movements like squats, bench presses, deadlifts, and shoulder presses. These compound lifts—especially done at a high intensity—are arguably the single best way to build functional, all-over strength. (It's called the Classic Iron Workout Program for a reason.)

To finish off Week 1, though, program creator Sean Collins, C.S.C.S., threw us a curveball. For Day 5, the head powerlifting coach of Murder of Crows Barbell Club incorporated unilateral exercises (aka single-arm and single-leg exercises) to target muscle imbalances. Traditional powerlifting moves are awesome, but they can also paper over imbalances between your right and left sides. By doing these unilateral moves, however, you'll target each side equally, giving both sides of your body time to develop. Think of it like a little change of pace—and watch your "main" lifts improve as a result.

Add in the stability-intensive abs work and conditioning-friendly box jumps at the end, and you're looking at a perfect all-around workout routine that'll burn plenty of calories while you're at it.

Here, Collins demos the workout once again to make sure you end the week on a high note.

Directions

Complete sets 1, 2, 4, and 5 as traditional straight sets. Do the two exercises in set three (3A, the biceps curl, and 3B, the dumbbell kickbacks) as a superset; complete both exercises back-to-back, resting only after finishing the dumbbell kickbacks.
