Good luck to you my friend. Ive been sitting on my ass too much in the past few months and the difference in energy and clarity of mind is night and day. I no longer go to my gym or pay for a trainer, but i have a bag at home which is an investment you would not regret if you take a liking to the sport. I also reccommend getting into a good stretching routine before you start because that will help you heal quicker and stronger. I excersise by doing yoga and hittinf my bag now, there are endless resources working out at home so its a decent alternative for me until I find a gym when I move.
