Yoga Ball 65 cm Diameter

Yes, the Yoga Ball 65cm is a very versatile accessory. For core work: the ball's instability engages the core stabilizer muscles more. For lower back and shoulder rehabilitation: recommended by physiotherapists. For office use: 2-3 hours/day maximum to reduce lower back pain. The 65cm size suits people between 165 and 185cm tall.

Yes, using a stability ball as an office chair passively activates the core muscles throughout the day. Recommendation: alternate between a traditional chair and the ball (2-3 hours/ball). Correct position: hips slightly higher than the knees, feet flat. Slightly reduced inflation (10-15% less air) for more stability in an office setting.

General guidelines: height <155cm = 45cm ball; 155-170cm = 55cm ball; 170-185cm = 65cm ball; 185-200cm = 75cm ball. For office use, choose the next size up so your hips are at 90° or slightly above your knees. For fitness exercises, the standard size based on height is suitable.

Check the maximum load capacity indicated on the product page. Quality balls are generally 'anti-burst': in case of puncture, they deflate slowly rather than bursting abruptly. For exercises with weights (dumbbells on the ball), check that the capacity covers your weight plus the loads used.

Inflate using a manual or electric pump until reaching the desired firmness. Do not overinflate. Store away from direct sunlight and heat sources that weaken the PVC. Clean with a damp cloth and mild soap. If it loses a little air, re-inflate regularly.
