What to do when your machine is busy?

Gym lines are bound to form during peak hours. The best option is to head to the gym during off-hours either early in the morning or after 7 p.m., once the post-work crowds have finished. But no matter how busy the gym is, you shouldn’t have to stall your routine in order to wait for equipment.

To get around this obstacle, always have alternative options in the back of your mind in case your preferred equipment is taken—for example a squat rack may be the best place for you to get in a heavy set of back squats, but as a swap, dumbbell goblet squats can be just as challenging and add an element of core strength. Come prepared with a Plan B and you’ll stay moving rather than wasting your time waiting for the bench to open up.
