Without goals, no one would unicycle the Appalachian Trail or train a flock of carrier pigeons to deliver meat pies to unsuspecting haberdashers. Today's Groupon helps you achieve myriad goals with a fitness trainer's expertise and motivation: for $40, you get four small-group training sessions at BalanceCore Fitness (a $200 value). This deal is valid for 50-minute sessions that include up to four people at a time.

The certified trainers at BalanceCore Fitness will whip you into shape with a results-oriented regimen focused on functional training for the entire body. Programs customized to your goals and level of fitness build strength and endurance through weight-bearing activities targeted at core muscles. While functional training is not recommended preparation for starring in oil-smothered muscle contests or Predator sequels, it can improve joint stability and prevent injuries commonly sustained in sports and daily activities.

Improve chronic bad posture with a program of medicine-ball training, which is designed to enhance muscular balance and control. Plyometric training can help fast-moving athletes increase their speed and explosiveness. A colorful and hygienic gym with spacious training areas and modern equipment ensures that customers have ample room to stretch their lissome bodies and retune atonal muscle groups.
