TRIGGERPOINTMB1 Foam Massage Ball, 6.6 cm – Deep-Tissue Compression for Targeted Muscle Relief, Ideal for Tension and Stiffness in Hard-to-Reach Areas of the Body for Enhanced Mobility

Expensive but worth it. Just the right comfort/pain level in use!

Best ball I've used. Firm but not rock hard. It's a good size, its light and the grippy foam outer is perfect for rolling them knots out. Very happy, exactly what ive been looking for.

Very effective, it worked for me

Bought to relieve back spasms and it’s fabulous

Great ball reaches the spot

Really good. I've had what feels like a brick in my left shoulder. After one use I could feel it kneeling the nodules and the pain is going away nicely 👌

I had a rhombus (major, I think) muscle problem recently. Very tight and particularly sore when I twisted my neck.A massage therapist suggested a tennis ball to roll it out, or better still she said a dense foam ball would be even better.So, I ordered this one and though it could be coincidental timing the affected are feels 10x better after a week of daily use. It is really quite expensive for what it is - just dense foam. So perhaps a cheap one would have worked just as well. But either way, it has worked very well for me for was money well spent.

Good but needs to be bit more solid (or harder) as it has gone slightly out of shape after it has been used a few times. (I am not overweight but 5ft 6 and just under 8 stone)
