Workouts for Knee Pain: What You Can and Can't Do
When your knee hurts, you want to leave it alone. After a month of rest, the quadriceps muscle weakens by 10-15%, and the joint it supported hurts more. The right amount of exercise for knee osteoarthritis reduces pain more than painkillers — this is stated in clinical guidelines. The question is not “whether to train,” but “what and how.” Section — workouts with joint pain.
What supports the knee
The quadriceps muscle is at the front; it absorbs impact with every step and descent. The glutes are at the back and sides; they keep the knee from collapsing inward. When both are weak — which is normal in sedentary people — the load goes into the joint. The goal of the program is to restore both without loading the joint itself: a shortened range of motion, a slow pace, and weight only when the pain has gone away.
8-Week Program
| Exercise | Weeks 1-2 | Weeks 3-5 | Weeks 6-8 | Purpose |
|---|---|---|---|---|
| Glute bridge | 2×12 | 3×15 | 3×15 on one leg | glutes, reducing knee load |
| Seated leg extension | 2×12 without weight | 3×12 with a resistance band | 3×12 with a 1-2 kg weight | quadriceps without loading the joint |
| Chair squat | 2×8 until touching the chair | 3×10 | 3×12 below chair level if there is no pain | quadriceps + glutes |
| Step-up onto a 10-15 cm step | 2×8 each leg | 3×10 | 3×10 onto a 20 cm step | knee control |
| Side-lying hip abduction | 2×15 | 3×15 | 3×15 with a resistance band | gluteus medius, preventing the knee from collapsing inward |
| Walking on level ground | 10-15 min | 20 min | 30 min | cartilage nourishment |
Rule of Three Questions
Does it hurt during the exercise — no more than 3 out of 10? Is it no worse the next day than before? Is it easier, not harder, after two weeks? Three “yes” answers mean the exercise is right for you. One “no” means a shorter range of motion, a slower pace, or fewer repetitions. If your knee is worse after a month on this program, see a doctor; this is not something to “work through.” Squats and knees separately — squats and knees.
Not allowed while it hurts
- Running, jumping, jump rope
- Deep weighted squats
- Large-range lunges
- Going downstairs without necessity
- Exercise bike with high resistance — low resistance is allowed
- Training while taking painkillers
What else helps
Weight — every kilogram means four less on the knee: knees and excess weight. Wear cushioned shoes for walking — not flat-soled sneakers. Use heat before training and cold afterward if there is swelling. Sleep 7-8 hours — cartilage recovery takes place at night. Protein 1,6 g per kg — muscle needs something to grow from.
Frequently Asked Questions
Crackling during extension — should I stop?
Without pain — no, that is gas in the joint fluid. With pain or locking — use a shorter range of motion, and see a doctor if it does not go away within two weeks.
Knee brace during training?
With instability — it is okay. Constantly — no: the muscle needs to learn to provide support on its own.
Swimming instead of everything?
Swimming reduces the load and is beneficial, but the muscles needed for walking and stairs are built on land. Swimming is an addition, not a replacement for bridges and chair squats.
- Walking with joint pain: cartilage lives through movementRest is hunger for cartilage: it has no blood vessels and is nourished with each step. How much to walk with knee and hip pain, what to wear, where to walk, and how to build it up.
- Back pain and core: what to train when your lower back hurtsFor people who sit, lower-back pain is caused by a weak core and inactive glutes, not a “disc”. Four exercises you can do from day one, what not to do, and when to see a doctor.
- Squats and knees: the myth that they are “harmful” and a pain-free techniqueSquats do not harm the knees — poor technique and using weight before you are ready do. How to squat with sensitive knees: a chair, depth, knees and toes, tempo.
- Vitamin D, K2 and bones: so calcium goes into bone, not blood vesselsBone is the foundation of the joint, and after 45 it declines rapidly. Vitamin D based on test results, calcium from food, K2 as a guide, and strength training, without which none of this works.
- Glucosamine and chondroitin: an honest look at the most popular joint supplementDozens of studies, half funded by manufacturers. The effect is small and not seen in everyone. How to test it on yourself for three months and avoid paying for a placebo for years.
- Omega-3 for joints: the dose that worksFor joint inflammation, omega-3 are needed at a dose of 2-3 g of EPA+DHA — higher than usual. What studies have shown for arthritis and osteoarthritis, fish or capsules, and time to effect.
