If you want to see new muscle growth, sometimes you have to take an unconventional route. This is especially true when you're trying to develop your abs and shoulders—two muscle groups that tend to get boxed in by the same few sets of exercises.

But consider this combination of four moves—1 1/2 squats, dumbbell pullovers, plank shoulder taps, and hollow rocks—your new roadmap to building mass, as well as strength and definition, in your abs, traps, and delts.

Directions

You'll do this workout as a circuit, meaning you'll complete each exercise consecutively without rest. Once you've finished all exercises, rest for 30 to 60 seconds. Repeat the entire circuit for four to six rounds.

Depending upon your ability, you may shorten or lengthen the rest periods between circuits. You may also complete more or fewer rounds.
