I have been reading this forum daily & I love all of the info! I feel so motivated and I feel like I have "fallen in love" with exercise again since discovering Cathe! I have read of several different recommended workout schedules, each one a bit different than the other. Some have 2 cardio days, others four, etc. How do I know what to choose for myself? My current schedule is 3 days of cardio and three days of weights, all for 45-60 minutes. Are the changes just based on what results I want or my preferences? Is this optimal for building muscle in upper body & conditioning lower body? Also, I push myself as hard as possible during all 6 workouts. Is this correct, or should I ever "take it easy"? Thanks for all help & comments!
