Clean, spacious, a good selection of machines/free weights, and conveniently located - what else can you ask for??? The black card membership is a must for the frequent traveler or oven someone who wants to explore a new location across town (there's several Planet Fitness franchises in the Charlotte area).
All in all this is a (4 star) good choice for the average person who just wants to stay in shape. However, not recommended for the hardcore fitness geek due to the lesser variety of free weights.
Btw, free pizza on the first Monday of every month! I know, this is kinda silly coming from a "gym" due to the obvious nutrition shortfall, but I'll take it!
