I used to run outside and didn't like it much either and now it's too cold anyway. That's why I invested in an elliptical. Personally, I think home equipment is a good investment if you know you're going to use it everyday. But you could also get a gym membership. There are a lot of options besides jogging or the elliptical, although I think the latter is a great exercise. You could bike, swim, use a rowing machine, or even do a circuit where you do 20 minutes on one and then 20 minutes on another. As far as duration, I would start small like 20 minutes and see how much you can handle. Eventually, you'll want to work your way up to 45-60 minutes per session. After 60 minutes, you'll see diminishing returns so it's not worth doing more than that.
i want to do exercise in my home but without having to buy a treadmill or expensive equipment,cos i am at home now (varsity vacation), but i wont beable to take any equipment with me when i have to go back to varsity..therefore i need exercises i can do indoors.
