Do Ab Belts Strengthen Abs?

Abdominal belts are used by weight lifters to help stabilize the spine during heavy lifts. Rather than strengthening the abs, they provide external support to the abdominal wall. Wearing a belt enables the use of heavier weights but reduces the ability to train and strengthen core musculature. To build abdominal strength, the National Strength and Conditioning Association recommends performing exercises without a weight belt when using lighter loads and wearing one only during maximal efforts.

Role of Core Musculature in Heavy Lifting

The spine requires stabilization during exercises like the squat and deadlift, which stress the lower back. The trunk muscles form a natural ring around the torso to serve this function. When executing squats and deadlifts without a belt, the abs, lower back, obliques and transversus abdominis muscles contract to stiffen and support the spine. As the weight being lifted increases, so does the stress on the spine. Weight belts are worn to enhance the natural hoop of muscle supporting the trunk.

Role of the Weight Belt

Weight belts assist in torso stabilization to reduce the risk of the spine buckling during heavy lifts. They are used to minimize injury with proper lifting and spotting techniques. Belts are most useful during exercises like the squat and deadlift, which utilize maximal loads and place high levels of stress on the spine. With additional trunk support, the lower body can safely execute heavy lifts.

Drawbacks of the Belt

Weight belts assist in torso stabilization but remain controversial and are not appropriate for some lifters and circumstances. Studies are inconclusive on whether weight belts provide significant improvement in overall strength. Wearing a weight belt changes motor patterns in the body that may increase injury risk during lifting when a belt is not worn. Training with a belt minimizes strengthening of the abdominal wall, which is detrimental to building trunk stability. Lifting with a belt also increases blood pressure and heart rate, and should be avoided by those with cardiovascular disease risk factors.

Strategies

According to the National Strength and Conditioning Association, weight belts should not be worn during submaximal efforts that stress the lower back. Sets performed with lighter weights should be executed without a belt to perfect technique and strengthen the abdominal wall. And athletes who require a stable torso during sport-specific movements should forgo a belt altogether.
