Nothing wrong with doing the tried and true exercises that help you get stronger while building lean muscle. However, on occasion it’s always good to mix things up to keep your muscles guessing for continued improvements in both performance and aesthetics.

One surefire way to help break through plateaus is to try some unconventional exercises that use stability training. By incorporating the following five moves into your workout routine, you’ll be sure to fire up your muscles and work areas that might not have been targeted in the past.

Give all five a try to chisel your physique from head to toe. Just be sure to take it slow until you’re able to master the movement.
