Bootcamp in Santa Rosa

Today they’re playfully dubbed “The Boot Camp Guys,” but Jaron Eliopoulos and Jeffrey Sears were merely students of kinesiology when they met in 2005. After bonding over a shared passion for fitness, the two began to move toward their current nickname by leading boot camp on the side of personal-training jobs. But when their camp spread to two cities and more than 100 patrons, the amount it takes to overthrow a tyrannical couch potato, Jaron and Jeff could ignore their calling no more and LiveFit Boot Camp was born.

Accountability is the glue that holds campers together at the sessions, which are held at parks all over the region. Jeff and Jaron dream up a new workout each day and turn it over to trainers who not only encourage the clients that attend, but also check in with no-shows to make sure they’re staying on track. Through combinations of sprinting, suspension training, kettlebell moves, and other exercises, the routines keep muscles guessing and attendees engaged.

Making use of the motivation provided by friends and the beauty supplied by local parks, the duo of instructors behind ecoFit takes troupes of women outdoors for calorie-busting exercise in the sunshine. Wendy Welling, who is an ACT-certified personal trainer, and Stephanie Evans, who studied exercise physiology and nutrition at UC–Davis, lead their workouts multiple times a day, varying routines throughout the week to provide quick results in increasing their clients' general levels of fitness and ability to tell the difference between Monday and Tuesday while blindfolded. As a grateful gesture to the community spaces that make this type of exercise possible, ecoFit gives 2% of its annual revenue to Santa Rosa city parks and California State Parks organizations.

Napa Valley Adventure Boot Camp owner Jeff Larson and his team of trainers know all about breaking a sweat. Each day, they challenge their students with fitness classes that string cardio and resistance workouts into a challenging chain of intense exercise. They also understand that water and electronics don't mix—instead of hosting their classes inside gyms filled with treadmills and stationary bikes, they stage their regimens outdoors, fortifying their workouts with rejuvenating sunrays and the encouraging shrieks of onlooking robins.

Most people attend boot camps to lose weight, not to get strong enough to fight the Taliban. But that's just how START Fitness founder Sgt. Ken Weichert got his start. The veteran of Operations Desert Storm and Iraqi Freedom and six-time Soldier of the Year is also a certified Army Master Fitness Trainer who pushes combat troops to reach the military's fitness standards in basic training—that is, actual boot camp. In START Fitness's weekday morning boot camps, the veteran transfers his field commands to the civilian realm in order to help everyday athletes lose weight, build muscle, and forge healthier lifestyles. Sgt. Weichert trained his team of seasoned instructors personally. They lead the camps which alternate between indoor and outdoor activity, calling on more than 100 lessons that constantly change up the workout to keep bodies guessing. The classes are designed for students who are already somewhat active, as they are intended to sculpt and tone as students go through obstacle courses, do push-ups, complete partner-assisted exercises, and run up to five miles without tiring or requiring a treat and an ear scratch after each task.

According to Red Tricycle, ACE-certified trainer and mother of two Kristen Horler founded Baby Boot Camp in 2001 to provide "child care and a gym experience without the high costs of needing to get a babysitter and a gym membership.” Kristen and her nationwide network of trainers foster more fit bodies and closer connections with exercises ranging from stroller workouts to surprisingly rigorous games of Got Your Nose. The inventive, varied routines culminate into a boot-camp experience designed to help moms and moms-to-be stave off excess body fat and depression.

Body Mechanix’s talented personal trainers, including a nationally ranked strongman and a Harvard grad, didn’t get buff all by their lonesome. Believing that encouragement and camaraderie make as much difference as weight and reps, they cook up ever-changing routines through collaboration with their fellow fitness gurus, a practice that allows them to share ideas and show off their ability to bench-press other bodybuilders. Individual lessons send clients sprinting across indoor stretches of turf or hiking heart rates with cardio and weight machines, whereas group classes help them sweat off inches with fast-paced boot-camp exercises or teach them how to jab out aggression with circuit boxing.
