Luckily I have access to a gym at school, so that makes doing the routines more convenient. But I'm gonna get some rings soon and hopefully a kettlebell. And you are right about how anything less seems pointless. I see people doing curl after curl and think "why in the world would I want to do 25 curls when I could be doing 25 L-pullups???" (which I actually CAN do).

I am a student studying Physics and Computer Science and I have found that exercising really helps me focus when I need to. It definitely makes me feel better every day to the point that I hate skipping even one session. I did P90X over the summer to take myself to the next level and am currently doing CrossFit (like the author). If you are into insane workouts that only take half an hour, CrossFit is the way to go! -Nathan
