The difference between a fitness class and a coached training session is accountability and progression. At Highland Mercer, every class format follows a periodized curriculum — meaning the work you do in week one connects to week four, builds through week eight, and peaks in week twelve. Your coach remembers your modification from last Tuesday. The warm-up isn't filler; it's targeted preparation for the day's primary movement. The cooldown isn't an afterthought; it's where your coach debriefs the group on what they observed and what to focus on next session. This is group training that accumulates, rather than a series of disconnected hard workouts.
