For too long, I have been out of shape, lazy, and otherwise lame. I play football with my friends, but I'm a goalkeeper most of the time, so I don't do much running. But I'm tired of that. So I signed up for a kickboxing class a couple weeks ago, and HOLY DJFKLA;SJFK!!!!!!! It's hard. I nearly passed out from exhaustion on my first and second days. It lasts an hour, and about 10 seconds in you already feel like you've worked out enough for a month. But it freaking WORKS. I've gone down a waist size in jeans already, and I feel a lot better in general. Seriously guys, screw running. Sign up for kickboxing. It's intense and incredibly difficult, but it's totally worth it.
