That is my question
Any remarks are welcome

However, I have a specific need for some suggestions for in-house gym stuff. It's a long story, but the juice of it is I don't want to go to a fitness club or walk outside. Never mind the reasons.

Are there any items or equipment that can help me exercise within my smallish man-cave ??? I need to do aerobic and other exercises in a limited space with small or no equipment. I do have a few small weights ..etc. And need suggestions for more equipment that is not electric (maintenance free , almost ) and can fold away in drawers or cabinets.

Suggestions are appreciated.
Oh, and any pdf materials online are welcome too.
Thanks
