Strong and Well-Defined Calf Muscles

The BOB Calf Master is a unique piece of exercise equipment that is designed to target the calf muscles. It is a compact, durable, and portable device that provides a highly effective workout to strengthen, build, and tone the calf muscles (gastrocnemius and soleus) as well as providing a very stretch mechanism for good flexibility. Here are some key features and what you need to know about the BOB Calf Master:


The Bob Incredible Calf Master is a simple effective tool for improving calf felibility. Helps plantar fasciitis, achilles injuries, and other ankle flexibility related issues.Design: The BOB Calf Master exercise device is a scalene shaped triangle (6 ¼” x 5” x 3”) with three unequal angles and three unequal surface sizes. The rounded angle between the two shortest surfaces provides a pivot point that enables the user, when standing on the platform surface, to move up and down through a full range of motion – dorsiflexion to plantar flexion using their own body weight as resistance. Being able to move the ankle through a full range of motion strengthens the calf muscles throughout the range while producing good flexibility. And, because of the role of the calf muscles in push-off, the BOB is an excellent tool for maximizing your workout.


Versatility: One of the truly unique benefits of the BOB is its versatility. These include:

  • As previously explained, it is used to strengthen and define the calf muscles.

  • It provides a highly effective strategy to stretch the calf muscles and the dorsiflexion muscle group by taking the ankle through a full range of motion during the exercise.

  • Its scalene triangular shape provides for a rounded pivot point to effectively challenge proprioceptive sensitivity of the muscles that cross the ankle joint for balance training and rehabilitative efforts.

  • The unique characteristics make the BOB an effective therapeutic device in the treatment of sprained ankles, Achilles tendon pathologies, and plantar fasciitis.

The BOB Calf master stretch system is an easy to use stretching device to help enhance a calf stretch, either as part of a rehabilitation regimen or sports training. What sets the BOB Calf Master apart from manual stretching is it helps keep the toes straight, not bent, which will help improve the effectiveness of the stretch.
