Hi, I've been taking reformer classes for about 15 years at a studio and I'm psyched to have purchased a reformer for home. I got (and managed to assemble!) an Allegro. I'm not entirely sure how to translate its footbar positions -- it has 3 -- which don't seem to be quite the same as the studio reformer. Are they intended to be the same as the studio reformer ones? Any advice would be appreciated -- I've googled and not found anything. Thanks in advance for enlightening me.
