In a push-up position, begin with your right hand on a dumbbell and your left hand on the ground.
Move your body down toward the ground, as in a regular push-up, and then return to the starting position. After completing one repetition, place your left hand on the dumbbell and remove your right hand, placing it on the ground to resume the starting position on the opposite side of the dumbbell. Again, perform a regular style push-up while keeping your left hand on the dumbbell. This is one rep. Repeat.
To perform a pull-up, hang on to any bar, doorway, tree branch, etc… with your arms straight and your palms facing away from you, and pull yourself up until your chin passes the bar. That’s it.
Pull-ups can be performed on anything that allows you to hang with your arms straight and your knees not touching the floor.
