If you're dealing with knee pain but want to make progress with your strength gains, the good news is that you don't have to nix all lower-body exercises from your routine. Low-impact exercises can help target your leg muscles without putting a lot of pressure on your knees.

When you overdo high-impact exercises, like running and jumping, it can put repeated stress on the patellar tendon — which connects your kneecap to your shinbone — which may lead to a condition called patellar tendonitis, aka jumper's knee, according to the Mayo Clinic. Patellar tendonitis is one of the most common causes of knee pain.

The good news is you can help treat knee pain from patellar tendonitis by strengthening your quads, calves, glutes and hamstrings, per the Mayo Clinic. When you strengthen these muscles, they help take the load off your knees and stabilize the joint.

For example, as gravity pulls the knee down while doing a squat or lunge, the soleus — the calf muscle that runs down the length of the leg — lengthens and helps slow down the ankle and knee as they bend, lessening the impact, according to the American Council on Exercise (ACE). Plus, strong quads can help the hip bend during exercise, which activates the glutes and minimizes stress on the knee joint.
