Directions
To keep the workout to 15 minutes, you’ll need a more expedited bench press warmup. Steadily work up in weight, resting only as long between warmup sets as it takes to change the plates.
This hustle means you won’t be optimally prepared to lift your heaviest possible load for 4 to 6 reps—so you should therefore use a slightly lighter weight—but that’s the tradeoff for getting the workout done quickly. To minimize the problem, rest two minutes after your last warmup set before you go heavy.
1. Bench Press
-
How to do it: Lie flat on a bench with feet planted on the floor, grip the barbell slightly wider than shoulder-width, then lower the bar to your chest and press it back up until your arms are fully extended.
2. Incline Dumbbell Press
-
Reps: 8-10
-
How to do it: Sit on an incline bench set at about 30-45 degrees, hold a dumbbell in each hand at shoulder height, then press the weights upward until your arms are straight, and slowly lower back down.
3. Parallel Bar Dip
-
Reps: 12-15
-
How to do it: Grasp the parallel bars with your arms straight and shoulders over your hands, lower your body by bending your elbows until your upper arms are parallel to the ground, then push back up to the starting position. Lean forward slightly to emphasize the chest.
