haha, so true. Many trainers at my gym as me “why do you do so many 30min workouts, what possible response can you hope to achieve in 30min?”
When i watch these trainers train, its slow reps, talking between efforts, 5-10min warm ups (who wants to pay for a warm up?), then 5-10min of “massage” (if you call it that) at the very end. All in all, they might do actually 10-20min of actual work, and i rarely see their clients sweating.
Takes my clients nearly 2-3months to be able to last a solid 30min without “dying”. They warm up before hand on their own and warm down on their own.
