Knees take a beating in almost every sport — sudden cuts, hard landings, repetitive pounding, and awkward pivots all load the joint in ways it isn’t always prepared for. The good news is that most non-contact knee injuries, including many ACL tears, are tied to fixable strength and movement patterns rather than bad luck alone.
This guide breaks down the exercises and movement cues that physical therapists and sports medicine researchers actually use to build more resilient knees, plus the mistakes that quietly undo that work. None of this requires fancy equipment — just consistency.
Quick Answer
Injury-proof your knees by combining three things several times a week: strength work for the quads, hamstrings, and glutes (especially the glute medius), single-leg balance and landing drills that train control, and a short dynamic warm-up before practice or games. Programs built on this formula, like the widely used FIFA 11+ warm-up, are associated with meaningfully lower rates of knee and ACL injuries in athletes who do them consistently.
The Core Exercises That Protect Your Knees
Squats and step-ups are the foundation. Bodyweight or goblet squats build the quadriceps strength that absorbs impact every time you land, cut, or decelerate, while step-ups (onto a bench or sturdy box) add a single-leg stability challenge that mirrors running and jumping mechanics. Keep the knee tracking over the middle of the foot rather than caving inward — that inward collapse, often called knee valgus, is one of the clearest red flags for ACL risk.
Single-leg glute bridges and clamshells target the glute medius, the small hip muscle that keeps your pelvis level and your knee aligned during a single-leg stance. A weak glute medius is a common reason the knee drifts inward on landing, so these are worth doing even though they feel almost too easy.
Nordic hamstring curls (or a slower eccentric hamstring exercise if you don’t have a partner or strap) build the posterior-chain strength that protects against both hamstring strains and the hamstring-quad imbalance linked to ACL injuries. Lateral and forward lunges round things out by training the knee to stabilize through a range of angles, not just straight ahead.
Finish with landing and cutting drills: practice sticking a soft landing from a small jump with bent knees and hips back, and work on decelerating before you change direction rather than pivoting on a locked knee. These drills retrain the reflexes your knee relies on in the split-second moments that actually cause most non-contact injuries.
Why a Warm-Up Program Matters More Than People Think
Structured warm-up programs like FIFA 11+ — originally designed for soccer but used across many sports — bundle running activation, strength and balance exercises, and plyometric and landing drills into a routine done before practice instead of a generic jog-and-stretch. Research reviewed by groups like the Academy of Orthopaedic Physical Therapy has found that athletes who do these programs consistently see fewer knee and ACL injuries than those who stick to a conventional warm-up, which is why many youth and club teams have adopted some version of it.
The reason it works is repetition: doing balance, strength, and landing drills two to three times a week trains your nervous system to control the knee automatically under fatigue and pressure, not just when you’re paying close attention to form. That carryover to game speed is the whole point.
Tips and Common Mistakes
Don’t skip the warm-up version just because you lift heavy in the gym. Strength alone doesn’t fix faulty landing or cutting mechanics — you need the balance and plyometric pieces too, ideally right before practice or competition when they carry over to how you actually move.
Watch your knee alignment, not just your effort. If your knee caves inward during squats, lunges, or landings, slow down and fix the pattern before adding weight or speed — reinforcing a bad habit under load is how injuries happen.
Progress gradually and don’t skip the eccentric work. Nordic curls and slow-lowering exercises are uncomfortable, which is exactly why athletes avoid them — but that eccentric strength is what prevents many hamstring and knee issues.
Build this in year-round, not just preseason. Programs show the biggest injury-risk reduction when done consistently through a full season, not as a two-week tune-up before tryouts.
If you have existing knee pain, swelling, or a prior ACL injury, check with a physical therapist before starting plyometric or landing drills — the exercises here are for prevention, not for diagnosing or rehabbing an active injury.

Knee injury prevention exercises FAQs
What is the single best exercise for knee injury prevention?
There isn’t one magic exercise — the evidence points to a combination of quad/hamstring/glute strength work, single-leg balance training, and landing mechanics drills. If you had to start with just one, single-leg glute bridges or step-ups are a simple, effective entry point.
How often should athletes do knee injury prevention exercises?
Two to three sessions a week is the standard used in most structured warm-up programs, done consistently throughout the season rather than only before tryouts or after an injury.
Can these exercises actually prevent ACL tears?
They can meaningfully lower the risk. Structured programs combining strength, balance, and landing drills are linked to fewer non-contact ACL and knee injuries in athletes who do them regularly, though no program can eliminate risk entirely, especially in contact sports.
Are these exercises safe for someone with current knee pain?
Gentle strength work is often fine, but plyometric and landing drills should wait until pain-free movement is confirmed by a physical therapist or sports medicine provider, since prevention exercises aren’t a substitute for treating an existing injury.
