Why waste your time?
Why trainers love it: You don't have to be a Winklevoss twin to row your way to winning shape—something that's nearly guaranteed if you keep up with indoor rowing. That's because it's a true total-body workout that, in Kanski's words, "torches cals."
"When done right, you are working everything from head to toe, with an emphasis on your back side," says Renee Peel, NASM-certified personal trainer based in New York City. "Essentially, it is the deadlift of cardio machines, because you drive off your legs, support with your core and grip and pull."
Where to start: Form is especially essential when it comes to using the indoor rower so head to YouTube to watch some tutorials. Then, Kanski recommends starting with 30 seconds on, 30 seconds off; or a slow 1,000 to 2,000-meter row.
If you want to level up: Go for 10 sets of 500-meter rows with a one-minute rest interval between each, per Kanski who's "sending prayers now!"
