My arms feel like paper bags now

So I just got back from Tabata class, and I think the title of this post speaks for itself.

A quick bit of backstory: I haven't been getting as much exercise these days as I used to, because it's cold outside and my daily allotment of exercise usually consists of walks around campus. I've tried using machines - i.e. steppers or treadmills - but those have never done it for me. I don't feel right working out on them.

Around the start of this week, I saw an ad for Tabata classes every Thursday this month, and I figured it'd be a nice way to get in some working out for the month. I had no idea what I was getting into.

As it turns out - and I didn't realize this because I didn't bother looking it up - Tabata is a form of high-intensity interval training, consisting of 20 seconds of incredibly intense workouts alternated with 10-second rest periods for either a set time or number of cycles. It was far beyond anything I had expected, and judging by the comments by the other people there I wasn't alone.

Now I'm worried about when my muscles are going to give out - I heard somebody mention in two days, which would be nice because it'd mean I wouldn't miss classes tomorrow. Figured I might as well get my blog posts in while I can still lift my arms. I'll keep you all updated on how I'm feeling over the next few days.

For now, on a scale of one to ten of exhaustion, I'd say I'm about a three, but I've had time to relax a little. I might have been a four a little while ago.
