i got this idea when i was taking my 2x a week class at a tech school, car repair for dummies, its not really called that but you get the idea. i had to hold the exhaust pipe while somebody attached it to the hole thingamajig. i held it in a half military press position for about twenty seconds and fatigue started seeping into my side delt. i figured it would hit my front delt, which is very easy to hit, but it got the side delt.
so today when i was fervently doing lateral raises i picked up a pair of 25lb dumbbells after my set and held it in a half military press and the fatigue immediately went right to the side delts.
is this a good idea or a waste of time?
