Intervals

So interval training was mixed in this week, with one day of elliptical sprints, and one day of slide board sprints.

Getting used to the slide board was pretty cool at first, but once the sprints started it was pretty rough and I almost busted my ass a couple times.

My posture is getting a lot better, and my lower back pain while sitting at my desk is virtually gone. Only issues now are my hamstrings tighten up whenever I sit down, so I'm forced to get up and move every so often(I'm blaming the Glute Ham raises).
