Thanks to the resistance of water, the activity is supposed to be super low-impact and restorative. It's exactly what it sounds like: You get on a bike, submerged in a pool, and peddle away while an instructor guides you. (It's just one of the super fun pool workouts that aren't swimming.) And that's when I came across aqua cycling.
But after a trainer recently told me I should try slowing things down a bit and work on improving balance, mobility, and flexibility, I decided it was time to consider branching out. We’re talking things like CrossFit, high intensity interval training (HIIT), or boot camp-style group fitness classes. Generally speaking, I’m the type of person who likes a hardcore workout that leaves me dripping in sweat.
