Hi all, I was wondering what everyone here does to keep fit. Personally, I played sports all througout school and did lots of hiking. I played hockey and rugby and practiced sambo through high school and entered university at 5'6 and 145 lbs - none of it fat. After 4 years of undergrad and not doing much except for Karate twice a week and doing a lot of running during the summers between school years, I weighed in at 145 lbs....a lot of it fat. In the year after undergrad, I decided to get back into shape and ran 10km every other day (and a 15 km once a week) in hilly terrain. At the end of that year, if I'm pushing myself, I can do a 10 km in 32:15 and I weigh in at 123 lbs....the catch is I've lost any muscle mass I ever had and my 53 year old father is stronger than I am - it's quite sad to get choked out by your old man. I'd like to gain some muscle mass back and do have a Bowflex machine in the house. What I'd appreciate advice on is are running the distances that I'm running and building muscle incompatible? Furthermore, is the Bowflex a credible machine for weight training? Any advice would be greatly appreciated. Thanks a lot!
