Short answer: TriggerPoint’s MB5 is a 5-inch foam massage ball for larger muscle groups like hips and shoulders. It’s multi-density EVA foam, machine washable, and light enough to pack. It’s the ball to pair with a foam roller, not a replacement for a small, hard ball.
Big ball or small ball?
A 5-inch foam ball spreads pressure across a wider area and gives a little. A 2.5-inch rubber ball, like the Kieba lacrosse balls, presses a smaller spot harder. Many people own one of each.
What the listing gives
5 inches across, model 303. The weight is listed as 5.8 oz in one place and 6.38 oz in another. The listing makes several recovery claims; we don’t repeat them.
How it compares
The TriggerPoint GRID 1.0 roller covers long muscles like the thighs. The MB5 reaches spots a roller can’t. Foam Rolling Basics covers technique.
Bottom line: a cheap, sensible add-on to a foam roller. Amazon sets the price.
