Another thing you should take into consideration is figure out how much free space you have in your house, so that your newly bought, huge treadmill won’t end up packed inside your closet because of the lack of room. Treadmills come in various sizes and some of them fold neatly, while others are rigid, or simply can’t be packed. Also, it’s best if you could exercise outdoors (on a terrace, a balcony, or even in your backyard), not only because the treadmill won’t bother your household’s furniture setup, but also because working in fresh air is better for your body. However during winter or bad weather, you’ll still have to exercise inside, so you must have a “plan B” solution.
