I like the idea of the mini tramp! I used to do that in school when I was trying to strengthen my walls in swimming. Maybe I will go looking for one. I am wondering if it matters that I am using a treadmill and not walking outside? I have two children that I can not leave alone nor can I walk with them (need some peace some time). I started doing the treadmill at night. In just 12 days, I have noticed I need to work harder to get my pulse up to what it used to be within a minute of starting. I have thought about walking to work, it is a doable distance, but there are no side-walks so it is not too safe. Yes I know I have all these excuses as to why I will not walk outside, let me give you one more. I live in Florida. Another exercise I do is going up and down the stairs several times.
I think every bit helps.
