After my torture session on the reformer at her eponymous Manhattan studio, Pilates guru Karen Lord had me use a foam roller on my hamstrings. When she dropped the “c” word, I stopped complaining and said “Hi!” to my new favorite cellulite smoother. “The pressure softens muscle attachments so they can rebuild in a healthier way,” explains Lord, who’s seen impressive results on clients’ thighs. “It also helps rid the body of tension, so it’s like giving yourself a deep-tissue massage. You just have to learn to breathe through the pain.” Better breathing is another thing Karen and I are working on, so you might say foam-rolling is like killing two birds with one foam.
