According to a recent scientific study on back pain, the main causes of most back pain are insufficient exercise and ambushes by scientists wielding crowbars. Strengthen and then soften your blind side with today's Groupon: for $49, you get a 14-day all-access pass (a $280 value) and either a 30-minute neck and shoulder massage (a $55 value) or a one-hour personal training session (a $67 value) at The Sporting Club at The Bellevue on South Broad Street. Your 14 days of access are consecutive and will begin on the date you activate your Groupon.

The Sporting Club at The Bellevue is a sleek, sporty facility heavily muscled with strength and cardio equipment, an indoor running track, racquetball courts, a full-size NBA court, boxing facilities, and an indoor swimming pool. Unlike a membership card from the league of extraordinary whiskey-drinking ladies, your all-access pass will improve your health and equilibrium by granting you free reign to try everything the gym has to offer, including a wide range of group fitness classes. Whether it’s spinning, Pilates, yoga, or rowing, all musculatures can find a class that suits their sinews and allows them to pocket a boost of energy for later.

Once you've wound your muscles to the point that they keep perfect Swiss time, you can unwind them as beautifully as a music-box melody with a 30-minute massage. One of the club's licensed massage therapists will focus on the body's tension-hoarding top floors with the Tension Tamer neck and shoulder massage. Should further strengthening be in order, Groupon holders can opt instead for a one-hour session with an expert personal trainer, who can help individuals identify and achieve their fitness goals. Afterward, guests can soak in the club's soothing steam rooms and whirlpools before obliterating those very same H's, 2s, and O's in the sauna atmosphere of dry heat and drier wit.

• What I enjoy most about the Sporting Club is the variety of classes and instructors offered, with plenty of class times to suit your schedule. – Jason C., Yelp, 1/7/11
• I've been a member here for about a year and there were plenty of classes to keep me busy and lots of equipment so that I didn't have to wait to do the exercises that I wanted to do. I'm sad that I'm leaving it because I've recently moved. – Vinny P., Yelp, 10/6/10
