The biceps curl is one of the simplest exercises yet one that is very often performed incorrectly.
The biceps muscle is the cable that moves the forearm, which is a lever. This action works in just about every position UNLESS the elbow, or fulcrum of the movement is directly under the weight. At this point, the biceps will relax since there is no direct load on it anymore.
IF this is the case, the most important part of the movement, which should be peak contraction under load, is either reduced or completely eliminated. In layman terms, that sucks!
The key to performing any exercise correctly is to keep the muscles under load throughout the entire set. When your elbows are forward, you’re allowing the biceps to “rest”, even for a brief moment and that makes for a very inefficient workout.
The next time you’re doing biceps curls, look in the mirror at your profile and see if you’re doing them correctly. Pull those elbows back and experience a whole new “burn” that you may not have been feeling before!
Stay Fit Forever!
