A strong man wrestles you to the ground to show off; a stronger man boosts your self-esteem and then accidentally breaks three of your ribs with a supportive hug. Learn the tenets of both strength and community with today's Groupon: for $30, you get four weeks of boot-camp sessions twice a week at Greenville Adventure Boot Camp (a $180 value). New boot-camp sessions begin every four weeks and are available Monday–Friday starting at 5:30 a.m.

Greenville Adventure Boot Camp's exercise-hardened boot-camp trainer Heather Coley buffs up bodies with a shifting whirlwind of activities to prevent boredom and steady doses of encouragement to keep her sweat donors motivated. During a precamp evaluation, Heather takes a few baseline measurements of each participant's physical stats to compare with their end results, reviews their medical history, patiently listens to their hand puppet's complaints, and discusses their fitness goals. The 60-minute boot camp’s intensity level is flexible, with newbies and hardbodies alike aiming to max out their own physical threshold rather than Sylvester Stallone's. During each class, Heather dishes out a rotating mix of exercises, which might involve sprints, weight training, core blasts, obstacle courses, rope jumping, livestock hoisting, barrel sledgehammering, and spinning. Boot campers should bring their own mats, water, hand weights (5+ lb.), and towels.
