Also, I use this resource all of the time:
Exercise & Muscle Directory
It's a directory of every exercise you can think of and more, organized by body parts and best of all, it has GIFs of the exercises to show you how to do it properly.
Example: Pick Chest, under Dumbbell choose Bench Press...voila:
Instructions
Preparation
Sit down on bench with dumbbells resting on lower thigh. Kick weights to shoulder and lie back. Position dumbbells to sides of chest with bent arm under each dumbbell. Execution
Press dumbbells up with elbows to sides until arms are extended. Lower weight to sides of upper chest until slight stretch is felt in chest or shoulder. Repeat.
Comments
Dumbbells should follow slight arch pattern, above upper arm between elbow and chest at bottom, traveling inward over each shoulder at top. No need to drop weights - see suggested mount and dismount techniques:
standard or
advanced. Also see mount & dismount from
special machine rack.
