This is my torturer AKA as the stride climber. I was up to 30 minutes at a time but whne my legs started hurting worse and I had to get test ran I quit. I got on it today after working all day and spent 20 minutes...that 20 minutes seemed like 2 hours! But I did it,now I just have to keep it up. I'm not real comfortable sharing my weight right now but will post if / when I lose.
Time -20 minutes
