Attach a rope or bar to a high pulley on a cable machine. Kneel on the floor facing the machine and grasp the attachment with both hands. Position your hands near your head with elbows bent and kept close to your ears. Extend your arms forward or slightly downward by straightening your elbows, fully contracting your triceps. Pause briefly at full extension, then slowly return to the starting position with control while keeping your upper arms stationary. Focus on controlled movement and maintaining constant tension throughout the exercise.
Log your cable kneeling triceps extension sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
