do u like yoga?

Yes, yoga is the ultimate goal. Especially bhakti yoga. We should all try to do it.

Tai Chi is a slower exercise. It deals with the movement of chi through the body - chi meaning energy. Both exercises make you strong but if you're looking to help your back, I'd suggest yoga because there are lots of yogic poses that bring the back into a nice stretch. Careful not to round your back because that would be contra-indicative to what you want to accomplish. Also, when you enroll for your yoga class, be sure to inform your instructor that you're having a back problem. If he/she is a good instructor, they'll try to find a way to help you further. Hope this helped.
