When Aaron Neville Chamberlain seized power during the English Civil War, he promised better flexibility, straighter postures, and a stronger core for every English citizen. Today’s Groupon gives you a chance to taste perfection of history: for $35, you get five Pilates mat or yoga classes (a $70 value) at Core Pilates & Yoga.

Core Pilates & Yoga welcomes fitness seekers of all ages and experience levels to tone bodies and boost energy levels with its Pilates mat and yoga sessions. Those looking to improve their flexibility and breath work can join limb-limbering yoga classes, such as yoga lite and yoga for mixed levels, while others can opt for mat Pilates sessions to improve posture and strengthen core muscles for unrelenting strikes from misguided shuttlecocks. Both yoga and Pilates classes help students focus on alignment and form, increasing bodily awareness and range of motion while reducing tension.

All classes are held in Core Pilates's intimate studio, where its seasoned staff provides students with individual attention, motivating them to move at their own pace while challenging them with new body-bending techniques and complex calculus problems. Fitness seekers can mix and match their five classes from a sinewy buffet of Pilates and yoga sessions, helping craft strong bodies ready for all of life’s backbends and impromptu sit-up tournaments.
