Without a well-rounded workout plan, bodies are easily pressured into endless hitchhiking trips by overdeveloped thumb muscles. Take the wheel of your own physical wellness with today's Groupon: for $49, you get a 12-session introductory On-Ramp CrossFit class (a $199 value) at BlackFin CrossFit in Orange Park. Sessions are currently scheduled on Mondays, Wednesdays, and Fridays at 6:30 p.m.; the On-Ramp program typically takes one month to complete.

BlackFin CrossFit's diamond-sculpted instructors push flagging bodies to the pinnacle of athleticism with intense and varied CrossFit training classes. The On-Ramp program's coaches introduce newcomers to a wide-ranging repertoire of functional movements that can add strength to a weightlifting routine, endurance to a daily jog, and power to a weekly square-dance circle. During each 45- to 60-minute class, trainers pit participants against a gauntlet of equipment that may include weights, medicine balls, gymnastic equipment, and kettlebells. Every sequence is scalable to each attendee's experience and abilities, ensuring an appropriate workout for everyone from grandparents to Olympic-hopeful grandparents.
