[TRNR] Gym ball (diameter 55cm) | GYM BALL 55CM TRAINER

The TRNR Gym Ball (55cm diameter) is an essential training tool that improves core strength, balance, coordination, range of motion, joint stability and postural control.
Adding instability to your workout will challenge and train your abdominal muscles, back and pelvic floor muscles.
This makes it perfect for strengthening those often neglected muscles and preventing muscle imbalances, back pain, and injury.
Although specifically designed for core strengthening, gym balls can also be used for a wide range of exercises targeting arms, hips, buttocks and legs.
It comes with a manual pump and TRNR's innovative dual tool that allows you to inflate the ball to the correct size (by aligning the two holes with the marks on the ball) and remove the plug (by using the forked end).
