If you have a gym membership, consider using a rower for some Pilates-style exercises, as TikTok user @hellooliviablog demos in this clip.
As for doing this at home, if you're not ready to invest in a reformer because you feel limited to one type of workout (or you think you don't have the space), consider a rowing machine. Or, check out the LIT Method Rowing Machine, which combines a rower with a resistance band training system, making it like a veritable reformer itself.
"The rowing machine could be cool for lunges," says Blumenfeld. With one front foot on the ground and the other foot or knee on the seat, slide the seat in and out; try lateral and reverse lunges. You can also do slider moves with your back leg on the seat, bending in and out (sometimes called a scooter), as well bicep curls using the rower handle while in a seated position on the rower, with some form of chest expansion," she says.
