Yeah, I think Joeiss is using it for situps too.
You definitely notice a difference in your arms and everywhere else. It's almost a full upper-body workout. Sooo good.
I just did 8 freaking levels in week 5 day 2. That's just insane. That's what I get for doing 51 on my exhaustion test..

My arms actually hurt for once, but that might be because I also had a really good MMA workout tonight too.
