Diamond II Reformer

Diamond II on Reformer: 30 Modifications for All Levels

Diamond II on Reformer is a fantastic core-and-hip control exercise from the original Reformer Pilates Card Deck, which features 48 reformer exercises designed to build strength, stability, and smooth movement quality.

This variation adds more range and coordination than Diamond I because you’re bending and opening the knees, flexing the feet, drawing the knees toward the chest, then pressing long again. It’s excellent for training lower abdominal control, hip mobility, inner thigh engagement, and that all-important Pilates skill: moving the legs without letting the pelvis rock.

The setup is simple: lie on your back. Place long loops on the fulcrum of the ankles. Press legs straight out, point and separate toes, arms by sides. Inhale, bend and separate knees, flex feet, bring knees toward chest, pelvis stays neutral. Exhale, press legs out and point toes. Repeat with control.

Below are 30 unique modifications for Diamond II on Reformer, offering options for beginners, intermediate movers, and advanced practitioners.
