I'd even suggest a slower approach to heavier non-runners. When I began I went 30 seconds and thought I'd die. (I was only at a setting of about 4.7 on the treadmill so I was not trying to sprint!) Well, I kept doing it and then would add small increments at a time.. like up to 45 seconds and than finally got to one minute, than 1.5 minutes. Now after working on this for a couple of months I can now go about 2 minutes OK. Its OK to be gradual and work your way up on the time. I've even done 5 minutes twice. Wear a heart monitor to know when you are overdoing it. Good luck everyone and keep upping the time just a little bit at a time - that seems to work for me and prevents injuries.
