Knee pain is a common problem amongst active adults of all ages and physical abilities. It can be caused by an injury or simply repeated stress on the knee. As part of rehabilitation, the muscle groups around the knee, such as the hamstrings and quadriceps, need to be strengthened progressively.

Suji employs the principles of Blood Flow Restriction (BFR) training, allowing you to continue exercising safely and effectively at lower stress loads, reducing knee pain and achieving strength gains early in the rehabilitation. Discover a series of personalised BFR training programmes on the Suji mobile app, designed to address your knee problems.

Suji – Your Recovery & Performance Companion

"I was completely converted"

Rich, a 30-year-old CrossFit member who sustained knee injuries from running, tells of his knee recovery and confidence building journey with Suji.

“It’s frustrating to think that I spent so much money in Pilates and physio; nothing fixed it. Before using Suji, I had tried to do a single back squat and as soon as I got below parallel, I would feel the pain in my knee. But now I feel I can actually start to build up those weights.”
