Size does matter in health clubs. You don't want to feel like one of those workout ants, following a trail of sweat to the next machine, and then have to stand and wait because of overcrowding. Try the Sports Club/LA's numbers on for size: 127,000 square feet over three floors, including six exercise studios and eight lanes in the pool; 50 private trainers; 120 weekly group exercise and yoga classes; two hoops in the full-court basketball gym. And the 4,000 square feet of the cardiovascular center is filled with more than 100 workout machines so there's no waiting, even during the 6 p.m. afterwork rush. There is a steep initiation and a monthly fee to belong to this megaclub, but in return you get to sweat in luxury surrounded by earth tones and mini-waterfalls. You also get access to the relaxing spa and an upscale hair salon. But what puts it over the top for us is the full bar. Yes, you can take your place next to the striver guys and execugals and join the not-too-exclusive Train and Trash club.
