Consider:</p> <ul> <li>Eating lots of sugary, processed foods increases inflammation throughout the body, which may cause pre-existing joint pain to intensity and generally make you feel less than your best.<sup><a target="_blank" href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4672013/" rel="nofollow noreferrer">7</a></sup> Alternatively, eating a balanced diet (especially one full of <a target="_blank" href="https://www.warriormade.com/krill-oil/free/" rel="noreferrer">omega-3 fatty acids</a>) may help reduce joint pain. <sup><a target="_blank" href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6142028/" rel="nofollow noreferrer">8</a></sup></li> <li>You're more likely to have knee pain if you're overweight.<sup><a target="_blank" href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4966641/" rel="nofollow noreferrer">9</a></sup> Because diet plays a crucial role in weight loss (even more important than exercise, though you'll get the best results with both), <a target="_blank" href="https://www.warriormade.com/content/diet/keto-101/" rel="noreferrer">eating healthy</a> can help alleviate joint pain by reducing the amount of strain and stress being placed on your knees.<sup><a target="_blank" href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4508090/" rel="nofollow noreferrer">10</a>, <a target="_blank" href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3406229/" rel="nofollow noreferrer">11</a></sup></li> </ul> <p>So if you're experiencing knee pain, a good diet along with the right fitness regimen can go a long way.</p> </section> <hr class="divider-50 divider-medium mx-auto"> <section id="section3"> <h2>How do I strengthen my legs with bad knees?</h2> <p>Resistance training, flexibility training, and cardio exercises are all good for strengthening your legs even with knee pain.</p> <p>A good place to start is by working out two or three times a week.

Don't be afraid to modify the exercises, or do half the reps that the workouts listed call for. Doing <i>anything</i> is absolutely better than doing nothing, so be proud of yourself for <i>any</i> workout you do for your legs and knees.</li> <li>Second, give your body time to adjust to these exercises. Don't do too much too fast.

Supported sit to stands</h3> <p>To perform:</p> <ul> <li>Stand in front of your couch or a chair. Position your feet so they're shoulder-width apart.</li> <li>Put your bodyweight in your heels; kick your butt back toward the chair, and allow your hips to bend. Your knees will follow.</li> <li>Touch the couch or chair with your buttocks*. </li> <li>Pressing through your heels, sit back up to a stand.</li> <li>Repeat.</li> </ul> <p><i>*If the chair is too low, add cushions to adjust the range of motion.
