That is a lot to recover from regardless of age and as my dad used to say..."Not a spring chicken anymore".
I felt unusually tired last night. There are just too many things sucking up the energy at times for me so I know the feeling. I have noticed there are many different workouts done by people on this board and it really is true that "you can only do what you can" and if/when you push too hard sometimes things happen. I feel that its best to lift regularly regardless of the weight lifted. Something is better than nothing.
Hang in there Shug!!
