This exercise does double duty working your biceps and core muscles. Isolation holds use gravity to increase the difficulty of an exercise without needing a heavy weight.

1.Stand tall with feet hip-width apart with a slight bend in knees.

2.Hold weights in hands at 90 degrees keeping elbows bent.

3.Lower one weight down at a time, keeping the 90-degree hold, core engaged.

4.Return to starting position and repeat.
