If you survive all 9,000 kettlebell swings, hand-stand pushups, dead lifts, pullups, wall balls, box jumps, and overhead squats, CrossFit 305 promises to make you so tough you could tie an alligator in a knot with your glutes. If you've never tried CrossFit because you're afraid of red-faced and spitting militant trainers, stop watching trashy TV — this ain't Scared Straight. The trainers here have better things to do than to bark orders — namely to explain the WOD (CrossFit-speak for "workout of the day"), to encourage members, and to correct improper form. The thinking behind CrossFit is that if you never do the same workout twice, you'll constantly confuse your muscles and you'll end up in the all-around best shape and at the highest functional fitness level of your life. Peter, Sean, and Alex are among the certified CrossFit trainers who will assist you at any one of the seven classes offered weekdays at the gym. A more limited schedule is available on the weekends, including a yoga class on Sunday. When you notice that all of those air squats have manifested themselves as a solid, high-riding, and sexy culo, you'll understand why CrossFit is Miami's gym du jour.
