Why? After all, it's just a gym. Here's why: The faux glitz and glamour so annoyingly present at many of today's so-called health clubs is nowhere in sight here. And it's not missed a bit, thank you. The space is small but has everything a serious gym rat needs, from free weights and a variety of cardio machines to aerobic classes and fitness consultations. The clientele is primarily Miami Shores, so the place is devoid of those chemically enhanced herds roaming Miami Beach. No shimmering, multilevel spa-o-rama, useless computerized gadgets, tanning salon, gift shop, laser-light shows, or infomercial staff straight out of central casting. The membership rates are competitive: $160 for three months; $270 for six; $449 per year. And even with its limited space, M Power Project is never so packed that waiting lists are required for certain machines. People come, do their business, and leave. It's the way a gym should be.
