I just recently got a road bike a month ago and bought the shorts and helmet for it this last week. Ever since my job ended over the summer, I have started working out everyday alternating between upper and lower body after being on a one year hiatus from weight training. So far, I haven't had an endurance problem with biking with the likely reason because I ride a mountain bike to and from college 2-3 times a day for the last year. Endurance takes time.

My main problem seems to be the inability to gain weight. I can take in 3000 calories a day and do minimal cardio but gain nothing in mass really. However, my goal is to get up to maybe 170lbs (from 160lbs now) with 7-10% body fat then start taking up Krav Maga because I wanted to learn martial arts for awhile now. My desire it to have a lean, compact form without excess muscle or fat.
