Ok, so I'm a thirty something guy, I've always been strong and broad shouldered, but for the last decade I've probably been carry an extra 10kg or so of blubber... currently weighing in at 105kg. My day job isn't terribly sedentary as I am on my feet a lot, but I do end up with a lot of computer/desk time. My back has suffered and I have "always" had very very tight muscles. Last week I was getting shooting pains behind one knee due to muscle tightness, which I put down to breaking in a new pair of shoes. My usual emergency response to issues is a deep tissue massage, but my friend didn't have a spot for 2 weeks. For some reason yoga popped into my mind so I found a beginners video and tried it - no prior experience, preconceptions etc... at all.
After 20 minutes every evening for a week:
Shooting pains behind the knee have totally goneThe tension in the muscles deep in my lower back has eased - previously the only thing that helped there was acupuncture, and even that was as effective as the yoga has beenAfter the first session I was so drowsy I went to bed at about 9pm and just lay there blissed out for two hours before finally falling asleepMy range of motion has already improved - I still have incredibly tight legs but toes are almost reachableToday I tried a new sequence and amazed myself by being able to hold Warrior Three Pose comfortably - strength and stability are already coming
Overall I've been really enjoying it, and I can feel the difference while I'm just walking around - especially the easing of tension around the lower back/pelvis.
This is the video I first found - I have nothing to compare it to, but it has been great for me to start with.
