This abs workout pulls double duty: It not only carves and tightens your core, but it also prevents lower back pain in the process, says Men’s Health Fitness Director BJ Gaddour. 

The routine consists of five core stability exercises: bird dog, hollow-body hold, front plank, side plank, and back plank. Each exercise hits your midsection from a different angle, sculpting and strengthening your midsection in 360 degrees, he says.

And since they’re stability exercises, you’ll train your core to resist potentially spine-damaging motions like rotation, flexion, and extension, Gaddour explains.
