In Bikram yoga, to "lock the knee" means 3 things: Straight leg (full extension of the knee joint) + thigh muscles (including quads) contracted + body weight even on the foot. This position provides a solid support for the knee joint, giving it lateral stability as well as allowing the hamstring on the back of the leg to be long and stretchable. Since your quadriceps were not "designed" to hold a contraction for a long period of time, during the posture, it's important to train them by sending the message over and over to them to contract, thereby improving their strength and stamina. All this leg work is a big part of what gets your heart rate up in this pose! Check out this video for more about locking the knee:

"I have always been active and used to run quite a bit, but that took a toll on my knees. When I originally started at Bikram Yoga St. Johns in 2016, I was looking for something to help my joints and lower back issues.
"For me the obvious benefits of regular practice have been decreased knee pain and conditioning for my low back. But more importantly I find that it really helps control my anxiety through the focused breathing. I am very conscious of my breathing in class and I find it transitions to other stressful situations in my life. When I found out I was pregnant I was so thankful that my doctor was so encouraging about continuing to practice throughout pregnancy. There is so much misguided information out there, and Kay has been an amazing resource through this journey.
"When I really started to show, my pesky low back issues started to creep up again and were exacerbated by a trip I had to take for work. I returned home with sciatica and could barely walk without limping. After just a couple of classes, my back improved again and I have had hardly any issues since. It sometimes feels daunting when I am getting ready to go to class at almost 8 months pregnant, but I always feel so good after and know the breathing and focus will help me when its time to welcome my baby to world!"
