Having bad knees shouldn’t keep you from your yoga mat. If you experience or have knee problems, chose a slow, alignment-based style of yoga such as Iyengar or Hatha yoga and ask your teacher prior to class about modifications you could do. Taking care of your knees in yoga will help you enjoy your practice more and move around more happily in your world. Yoga strengthens the muscles in the lower and upper legs, which protects and stabilizes the knee joint. Performed correctly, yoga’s fluid movements allow swollen or otherwise painful joints to glide smoothly over one another, increasing mobility and strength without excess wear and tear. Yoga is a safe alternative to weight-bearing exercises that could worsen knee joints because yoga strengthens the muscles around them, which reduces tension and increases mobility.
