10-Pack: To stay motivated during bikini season, I said goodbye to a six-pack and hello to a 10-Pack. But in this case, a 10-Pack is the multi-studio fitness class card with access to top studios such as Flywheel, Core, Stellar Bodies and others at a discount. Categories include cardio, bikini, power and stability, allowing you to customize a plan that mixes spinning, kick boxing, yoga and more to achieve your personal goals in a fun, fit and social setting. Cards range from $186-$200, with an average savings of $43 per package. Mix it up and work it out.
