I bought myself a treadmill deciding i was going to start exercising regularly. being told music is a great motivator and distracts you from the tedious tasking of walking/running like a hamster in a wheel. I learned yes it does but on the other hand make sure you are walking/running fast enough to not get carried away and start singing and dancing as this will make you crash into a wall and get ambushed by a 3 month old puppy who will start jumping/ licking/ and bitting you in places that already hurt...... maybe i should just sell the treadmill
