While most suckers shell out hard-earned money for a chance to sweat it out at the gym, personal trainers actually get paid to be there. They must be doing something right.
Like any professional, they keep some secrets of the trade to themselves... most of the time. Fortunately, there are trainers out there willing to spill their confidential gym hacks, which you can use to feel like a seasoned vet the next time you work out.
Maximize exercise with active rest
Taking a rest between movements is fundamental to exercise, but practicing active rest allows you to squeeze every last bit of effort out of your workout. Ramon Acosta, Jr., trainer at New York City's ConBody, has a rule during his 60-minute sessions: always be moving. If students are caught stationary, they must pay the price of 10 burpees.
Of course, Acosta doesn't expect clients to be pumping out push-ups or HIIT intervals during active rest. A simple salsa step or walking in place will do.
Turn your phone into a smarter stopwatch
Louis Coraggio, an NYC-based trainer and founder of trampoLEAN, prefers apps that take basic stopwatch functionality to a higher level -- like Interval Timer, which makes it easy to set Tabata and strength intervals. "Each interval has a work and rest timer," Coraggio says. "It keeps my workouts focused and easily times out of my exercises."
