If i'm starting to exercise again, how slow should i start off?

Slowly enough that you don’t injure yourself and give up.

It looks like the torso track is an ab machine. August wasn’t that long ago. I think you’ll find what you had will come back quickly. Abs 2 or 3 times a week for 15–20 min would be plenty. I would make sure you continue the jogging or some other aerobic activity 3 or 4 times a week.

I’ve found for myself if I try to do more than that, I get burned out. Unless you have some specific goal or reason to do more than that…

I would guess your body will tell you. Your stamina might be a little down, and maybe do a ¾ work out for muscles and see if you get very sore or not. If you are a woman know that lung stamina comes back slower than for men, because our capacity is smaller, so don’t get discouraged if you can’t keep a jog pace up for very long, just walk the rest, it will be back to August level soon.

If you are a senior in highschool, it is essential that you get a good start on your adult body. In order to be sure of what you need, see your doctor and get some professional advice.
