Led by certified strength and conditioning specialist and four-time NCAA All-American Art McDermott, Fitness Revolution’s professional trainers encourage men and women of all shapes and sizes to set healthy goals, providing personal attention and supportive instruction. In brisk sessions of 45 minutes, intensive boot-camp classes help torch calories and chisel flabby frames into muscle masterpieces that would send Michelangelo's David into a jealousy-fueled Cheetos binge. Trainers utilize a 3,000-square-foot facility to march sluggish muscles along the pathway toward better fitness, eschewing spittle-laced tirades for cheers and nonthreatening back slaps. Fitness routines constantly vary, as trainers prescribe stronger doses of medicine balls and check the tone of barbells to ensure that they resonate with increasing levels of strength. Because getting buff requires a brawn-building balance of diet and exercise, a certified nutritionist offers nutritional recommendations to help students make educated nourishment decisions and deflect the cinnamon roll’s siren song. With rolling start dates and diverse session times, Fitness Revolution eliminates the excuse of scheduling conflicts and allows students to develop the bodies of their dreams whenever they see fit.
