 Our story

Questions

Which stress ball firmness is right for me?

Soft is best for gentle relief and early hand recovery. Medium suits everyday squeezing at your desk. Firm is for grip training. Not sure? The Tri-Density set gives you all three.
Which flex bar resistance should I start with?

If you're new or recovering, start with Light (red) and move up as your grip gets stronger. If you're rehabbing an injury, check with your doctor or therapist first.
