When I teach a power class, one where I'm really pushing my students I will get feedback telling me how much they loved the class and how they feel like they are going to be so sore tomorrow. I notice the next week that my class has generally grown a bit, like the word got out that if you want a good workout go to Jamie's class.
This got me thinking. Why do we think and like for that matter, when a class kicks our butt? I'm just as guilty as the next person. I started circuit training about six months ago and I swear I've been hurting since the beginning. I was overexercising, but aside from the pain, loving every minute of it.
Soreness after a workout is good, it means you are building muscle. The soreness should gradually build in the hours after your workout and then slowly fade out. However localized pain that reoccurs each time you exercise or if it persists between sessions could be a signal that you are doing too much. Sprain, strains, stress fractures or tendonitis are all signs of doing to much. Yogi's are not immune from this. Actually we are some of the worst offenders.
Power, Vinyasa, Ashtanga and Bikram yoga are some of the most intense yoga practices. These classes will push you to your edge. Unless you are an advanced yogi, and by this I mean that you have great body awareness and can let go of your ego, you are bound to hurt yourself eventually. There are people of all levels in these classes and a teacher can't cater to all. We will throw in the easy poses as well as the hard ones to make everyone happy. It is up to you to not go beyond your edge. As a teacher I see people do this all the time. The following week they come back and tell me how their shoulders/knees/hips hurt. I tell them to slow down and not go as hard, only to watch them do just that in the class.
A teacher will tell you to stop or slow down your practice in order to heal, but we can't make you and we won't adjust our class to tame your ego. It is up to you to sit down and check in with our body. See if the exercises that you are doing are serving you or hurting you. If you find that you have been overdoing it, the next step is to figure out why. Check in with your emotions and thought patterns here. Are you afraid of gaining weight or do you like the high that exercise gives you (that's my culprit). You have to decide if the emotional gain is worth the physical pain and potential permanent damage.
Your body is a temple, treat it with respect. Find a healthy middle where you challenge your body, but not overdo it. It takes a lot to let go of the ego, to let go of the exercise high of really challenging yourself. The key is to find ways that still physically challenge you (I switched to a strength class in the pool, nicer to the joints but I'm still reaching my goals), but don't damage your body in the process. You can get all the benefits of a healthy life with a lot less pain.
