Hard to imagine a nicer spot for a fitness class: this new Crunch Fitness Center is airy, and the views can't be beat.
As for the classes... Club Med has partnered with trendy Crunch Fitness, very popular in New York, Chicago, etc.
If you just want to work out, Club Med Punta Cana has an air-conditioned gym that's also styled by Crunch.
