PERFECT DESIGN: 5" in length and 2.5"in diameter, weight in 12oz. This split peanut-shaped massage ball is a perfect design to get to those hard-to-reach stabilizing muscles that surround your spine and vertebrae without applying pressure on them as you lay on it.
DURABLE MATERIAL: The massage ball is made of 100% natural rubber, which is firmer than tennis ball, but not like the hard plastic balls with knobs and they hurt.
FREE CARRY BAG: This Double Massage Ball comes with a bag to carry, perfect for use at the gym, on the road, before or after workouts.
WORKOUT GUIDE: The massage tool is comfortable and easy to use according to the instructions. You can use on painful localized parts of the body where trigger release is required while strengthening your core to stabilize.
