I am 53 year old, 5'10" - went Paleo after reading Mark Sisson's "Primal Blueprint" in May 2010. Went from 210 lbs to 183 lbs in 5 months. Diet includes Dairy,(only home made yogurt and cheese) - NO grains and only butter, ghee, EVOO, used for cooking. This weight loss was accomplished by just diet change and a daily 45 minute leisurely walk.
During my entire 53 years I have NEVER exercised in any serious way or played any sport - i do not even know how to swim. I was/am a nerd, I am an accomplished scientist.
My weight has kind of plateaued for the last 2 months and I am inclined to begin a workout program that I can manage on my own and something that I can sustain.
I tried to follow Mark Sisson's advice - "Primal fitness" - not surprisingly, I could not do even one pullup or even one pushup, (I managed to do several squats though).
My question to all here is - Where does a motivated beginner go for a fitness program. I have thought of joining a gym, but my location and schedules will only allow a home based approach for now. Are there any good programs out there which one can subscribe to or purchase outright that will guide a greenhorn like me to do some good workouts at home. Any other advise about the above situation is also very welcome.
