honestly, when i workout, i do not worry about what i am doing for my workout....
Wednesday's is my league night and yesterday for my workout i ran 3 miles, and then did Back and Biceps....
I've had other times, that I workout my legs before my league by doing Leg Press's / Squats, leg extensions, hamstring curls, calf raisers and deadlifts.. It has not affected my bowling at all...
And same goes for when I am playing softball, I just stick with what I am planning on working out for that day....
