Foam shafts are usually made of lightweight, cushioned elastic materials such as EVA, PVC or TPE. It is cylindrical in shape, with a standard diameter of about 15 cm, and the length is 92 cm, 46 cm and 36 cm. In addition, there are special types such as short foam shafts and mace foam shafts to meet the needs of different users.

Second, the role and efficacy of the foam shaft
Relax muscles with fascia:
The foam axis massages the muscles and fascia by rolling, helping to relieve muscle tension and stiffness and reduce muscle soreness and fatigue.
It can separate the muscle adhesion caused by sports injuries, promote blood circulation, and speed up the recovery process.
Improve joint motion:
Foam axis relaxation reduces tissue pressure, helps maintain joint range of motion, and increases overall athletic performance.
Enhance core strength and balance:
Foam shaft training works the core and improves stability and balance.
Prevention of sports injuries:
Using a foam shaft to warm up before exercise can improve muscle stretch, flexibility and elasticity, thereby reducing the risk of sports injuries.
Third, the use of foam shaft
Basic scrolling tips:
Place the muscles that need to be relaxed on the foam axis and roll slowly on the foam axis repeatedly with your own weight.
Keep the core tight during rolling to ensure stability during the action.
Relax in each area for about 1-2 minutes, and if you feel pain during the rolling process, stay on the pain point for 20-30 seconds until the pain level is reduced by 50%-75%.
Relaxation for specific areas:
Upper back: Lie on your back on a foam axis with your hands on the back of your head and roll back and forth to relax your upper back muscles.
Low back: Lie on your back in a small bridge position, place the foam axis on your low back, rotate your pelvis to lift your hips back, then relax and fall.
Front of thigh: Lie prone on the cushion surface, place the foam axis on the front of the thigh, support the elbows on the cushion surface, tighten the core, and use the strength of the body to roll back and forth to relax the front muscles of the thigh.
Lower legs: Take a push-up position, support your hands on the yoga mat, push off with one foot, place the lower leg of the other foot on the foam axis, and roll back and forth to relax the calf muscles.
