What r the best classes to take in 24 hour fitness?

Im thinking of joining 24 hour fitness and im wondering what is the best cardio class and what is the best strength training class in 24 hour fitness?? Or witch 1 do u recommend i try.|||Do interval training. You'll get more bang, in less time. I mixture of strength training with cardio. It'll help in the long run.|||The only time worthy class at 24 fitness in my opinion is 24 Cycle (Spin Cycling Class) but with a good instructor. If not, just work out on your own.|||the Zumba fit class are nice, plus you get to see a lot of ladies =) , but i actually like doing the water volley ball ! its really run !
