"Achieve shoulders that are lean and strong."
The CrossToner delt flex exercise precisely targets the deltoids of the upper back and middle of the shoulder blades.
Hold CrossToner behind head by both long handles such that short handles face upward. Slowly compress long handles until they touch directly behind neck.
Hold for 1 second, then release slowly.
Repeat 8-12 times.
Same as above except hold CrossToner so that short handles face floor.
