Can run for 40 minutes, sweat like a pig, but be okay on cardio.

Can run faster for 12 minutes, be a little and do another 30 minutes of lifting and be ready for my day to be over.

But give me 5 minutes of live drills in jiu jitsu after 40 minutes of warm ups and practice and I'm on my death bed PLUS all kinds of achy the next day.

You think you're in shape sometimes...
