Try the eliptical for cardioOriginally Posted by Pnogal5
Running trashes my knees also.
Fatloss can be as quick as you make it
I just lost 30 lbs in 8 weeks totally naturally by doing diferent forms of cardio 30-45 min/day (morning) and weight training 1 hr 2days on 1 day off
Also my diet consisted of strictly meat leaves and fruits
I would let your tendons,ligaments strengthen before considering steroids as they will be a weak link
One last point is that your body is currently producing more gh and more test at 18 than some people inject so capitalize on it = heavy compound exercises
whatever you decide goodluck
