I'm a 26 year old male. 145 pounds 5"10'. I've got Super DMZ RX 2.0 that I was going to start using the end of last year but moved and no longer have a gym membership. When I did have a membership I would lean up but could never really build muscle like I wanted no matter how hard I tried. I eat all the time and never really gain.

I currently bike about 15-20 miles a day with a road bike. As well I do what I can with out a gym. I was wondering if I kept biking and started a Super dmz cycle and did what I could outside of the gym. I've got access to insanity dvds that I could start.

What I want to achieve is getting some bulk in my shoulders/chest but still lean where I can still bike.

Any advise would be helpful.
