Pilates tightens cores, which is great for improving posture, strengthening stability, and creating a rolling terrain with a belly-button trench for epic army-men battles. Keep flesh soil in proper formation with today's Groupon: for $65, you get two private Pilates sessions at Spring Pilates Studio on SE 28th Avenue (a $130 value).

Spring Pilates' marble-sculpted instructors tighten and tone flagging physiques with patient, attentive direction and state-of-the-art equipment. Commit cores to the Pilates method for two private sessions, in which fledging fitness fanatics will work individually with instructors, honing their skills and progressing on a mat and Pilates equipment.

Spring Pilates customizes classes from hundreds of exercises, artfully crafting routines to reduce back pain, arthritis, and poor posture, as well as creating specialized Parkinson's, surgery preparation, and maternity classes. The regular group session provides a forum for support and camaraderie, and the opportunity to form a really lean and limber human pyramid.

Five Yelpers give Spring Pilates Studio a perfect five-star average:

• I have noticed a difference in my posture since beginning my training at Spring. I feel stronger, taller and more flexible! The studio is light, airy and well equipped with all the latest equipment. I look forward to my classes every week at Spring and highly recommend the studio to everyone. – Lindsay E., 3/23/10
