Aquatic exercise
Training in water unloads painful joints while you keep moving. Cochrane-reviewed for knee and hip osteoarthritis.
Why
Pool-based exercise uses buoyancy to cut joint load while preserving resistance, making it the workaround when land-based training hurts too much to sustain. The Cochrane review in knee and hip osteoarthritis (13 trials) found small but clinically relevant short-term improvements in pain, disability, and quality of life. The strategic value is continuity: it keeps the training habit alive through painful phases.

How to do it
How
2–3 sessions weekly, 45–60 minutes: water walking, aqua aerobics, or swimming. Most public pools run structured classes; consistency beats intensity.
Ideal for
Knee/hip osteoarthritis, higher body weight, post-injury return-to-training, anyone whose joints veto walking volume.
Sticking with it
Book a recurring class slot — pool habits survive on schedule, not motivation.
Evidence
Cochrane 2016, 13 trials (n=1,190) — aquatic exercise produced small short-term improvements in pain, disability, and quality of life in knee/hip OA, moderate-certainty evidence. Bridge value: it keeps you training when land work is off the table.
