Hi,
I'm new to the boards, and new to working out

I'm a Canadian, based in London, UK, and working for an animal rights charity.
As an unfit vegan, just starting out a workout regimen, I'm really struggling. The goal is to lose the gut and build muscle. Being motivated by action, I found a muay thai trainer who I am seeing twice a week. The plan was muay thai on Monday and Friday, and weights on Wednesday. The mauy thai trainer works me hard, and leaves my muscles exhausted. The problem is that they are still sore a week after a work out, preventing me from working out again comfortably.
Is this pain normal? Is it because I am new to working out? Is there something I can do to speed recovery?
I take hemp and pea protien right after a workout, and twice a day. And eat a high protien vegan diet with lots of sprouted beans, tofu, seiten etc.
I am reading through Robert's book now, hoping to find some help in there. In the meantime, do you have any hints, tips or instructions as to how I might speed recovery? Do you know of any supplements that might assist me? Any advice will be very much appreciated.
Cheers,
Blish
