Knee Trainer is a daily knee exercise program you can do at home in 8 to 20 minutes a day. Answer a few questions about your knee, and Knee Trainer builds a plan around where it bothers you, how it feels and what you want to get back to.
BUILT AROUND YOUR KNEE
• Show exactly where it bothers you on a simple knee map, front and back, left or right
• Tell us what it feels like and which everyday moments are hard: stairs, standing up, walking, kneeling
• Get a knee profile and a 6-week plan that starts gently and builds up
A SHORT GUIDED SESSION EVERY DAY
• Clear step-by-step exercises for the hips, thighs and knees
• Rep counters, hold timers and rest breaks, so you always know what to do next
• An easier option for every exercise, and a quick check-in before and after
• Your level adjusts to how each session felt
SEE YOUR PROGRESS
• Track how your knee feels, week by week
• Re-check everyday wins like stairs and getting up from a chair
• Finished sessions can be saved to Apple Health as workouts
1-MINUTE LESSONS
Short, plain-language lessons on how knees work and how to exercise with confidence.
