1. G-Box at Gotham Gym
Want to look like Gigi Hadid or Bradley Cooper? You have a solid shot with this group workout that was designed by celeb trainer Rob Piela of Gotham Gym. You start with a warmup (jumping jacks, jump squats) and then go through the basics—jabs, hooks, uppercuts— along with how to successfully duck a punch. After learning the skills, you partner up and try the new moves out while clips from movies like Rocky play in the background. And no class would be complete without some solid ab work. 43 Crosby St (917-472-7384, gothamgymnyc.com)
