ClassPass is one of the greatest apps/services out there, in my opinion; it lets you take classes at hundreds of studios (up to three at each studio and an unlimited number of studios) per month for a flat rate. Through ClassPass you get access to everything from spinning and martial arts to burlesque and yoga. I am completely addicted to it and take at least five classes through them each week. If you're looking to jazz up your workout routine, give it a try. Use this link to get $20 off when you sign up for ClassPass!
