Is this effective at all? Your opinions of LSD running on a treadmill would be cool as well. Can you gain explosive power from doing sprints on the treadmill? I always feel like i'm getting more of a knee to ankle workout more than all the way to my hips and mid section as far as static movement goes when sprinting on a treadmill. It feels like theres no push-off effect from running on this piece of equipment, as if you only jump up to keep your feet moving as the belt does... Any tips or info would be greatly appreciated!
