Changing up my shoulder and back routine

Good morning! off to the gym this morning for some shoulder and back work followed my 35 min stair climbing. Changing up your exercise routine is important! Your muscles adapt quickly so change is GOOD in this case. This morning one of the exercises I'm changing is a front shoulder raise, changing it to and underhand grip with an E-Z bar. I usually use dumbbells with palms down. 4 sets 15, 12, 10, 8 E-Z Bar front raise! Off to get my sweat on!
Cheers!
