I am currently doing a workout routine with my hubby that we have put together. We will eventually change over our routine, to keep it fresh but are doing well so far. We do change up the exercises for each body part so we aren't just working the same parts of the muscles.
I started with full body workouts, then after a week, went to splits. I'm working my way back into working out, so steady as she goes....lol
Sounds good and sounds like you have a good plan which is the key.
Work hard. Enjoy.
