Perspiration gets mischievous when cooped up inside the body, acting out by drenching armpits on first dates and disguising itself as tears during job interviews. Release disgruntled body water with today's Groupon: for $49, you get 15 CrossFit classes at CrossFit Primus in Owasso (a $225 value).

CrossFit Primus's intense namesake workout serves as the chosen bulk-building regimen for police academies, military troops, and martial artists across the world. One of the studio's three certified trainers helms each sweat-inducing session, which touts a scalable regimen to challenge both the neophyte exerciser and the human tow truck. Classes incorporate a variety of moves reliant on barbells, pull-up bars, and suspension rings as exercisers test their tendons with moves such as dead lifts, squats, handstands, jumps, and sprints. Each day welcomes a fresh class curriculum, blasting through traditional exercise plateaus like an elephant romping in a moon bounce. For fledgling CrossFitters, the gym offers a complimentary Saturday session to introduce the program, and all newbies must complete the course prior to enlisting in regular classes, which take place six days a week.
