Although gyms are tucked almost in every corner of USA, the cost of gym membership varies. How much are you willing to pay for maintaining your fitness schedule? If you want to boast of your hefty gym membership, head out for one of the upscale gyms in Los Angeles, New York or Miami. Popular venues for celeb sighting, these fitness centers can charge you anything between $80 and $500 per month. However, if you are planning to receive your fitness training from Madison Square Club in New York, managed by celebrity fitness instructor David Kirsch, the most expensive gym in USA will make you poorer by $26,000 per year.
