How long do you think I should use it for?
Start off short, say 10 mins or so per session. After you've done it a couple of times increase the time and load gradually. Ease yourself into it over a couple of weeks or longer. Also important to get a rest day or two every week. Rest is necessary for your body to repair the "damage" caused by the exercise and it's at this time that the muscles grow stronger.
