Ditch the free weights to target your muscles even more.
The fitness world is increasingly focused on barbells and kettlebells, but machines can still find a place in your regular workout.
As trainer Sean Garner explains, machines offer a perfect way to train safely if you're dealing with an injury, and veteran gym-goers can get a lot of mileage out of machine training, too, isolating and focusing in on certain muscles.
The key to using machines is to maintain a tight body position and a tight core, even though you're often sitting down.
It's easy to slouch on a seated machine, just like you might slouch in a chair, but you should work to keep your core tight and maintain good posture, keeping your shoulder blades tight.
In the video above, Garner demonstrates a full-body circuit with the seated chest press, seated chest row, lying hamstring curl, and leg press. Give them a try during your next workout.
