Concentration Curl

Isolates the biceps through a seated, braced curl that minimizes momentum for focused arm strength.

Sit on a bench with legs spread and lean forward slightly, bracing your elbow against the inside of your thigh
Hold an AguaForce weight in that hand with your arm extended toward the floor
Curl the weight up toward your shoulder, squeezing your bicep at the top
Lower back down with control and repeat before switching arms
