I have been spinning for 7 years. This winter I am doing it 2x per week with one 2 hr class. Prior to the class I lift for the chest, arms, back, and hips.
The other 2 days in the gym I work with the lower body. The only thing I really dont do is the calves directly. All other parts of the legs and butt help.
I work on abs all 4 days alternating the type of training.
46 and going strong. 2500 miles last summer and it is short here in wisconsin.About 8 good months....
