Alan “AJ” Vidlund might have had some hint of what he wanted to do with his life when he was playing baseball as a five year old. He grew up in an athletic family and went on to earn a college degree in fitness, and he's now the owner of LiveFit Boot Camp Greater Sacramento. He's also a certified trainer, and he'll jump in to lead boot camps there as well.

These camps keep muscles guessing and attendees engaged with combinations of sprinting, suspension training, kettlebell moves, and other exercises. Trainers will also check in with no-shows to make sure they’re staying on track, including LiveFit's founders Jaron Eliopoulos and Jeffrey Sears. Today they’re playfully dubbed “The Boot Camp Guys,” but they 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.
