I usually gravitate towards heavy dumbbells and barbells for my upper-body workouts, but some recent shoulder pain has made me pause my heavy lifting. In search of something gentler on my joints, I came across Kristal Ruiz’s "killer arms" Pilates routine on Instagram.
Don’t let the name intimidate you—this upper-body workout is relatively easy to follow and suitable for most fitness levels. You’ll even get some glute, core and hamstring work along the way.
