Also, you can change
the focus of the exercise by simply adjusting your foot position — a higher foot position will hit the glutes more effectively, whereas a lower foot position will primarily engage the quads.
By moving the weight in front of you instead of behind you, you change your center of gravity and, thus, change
the focus of the exercise to the quads.
Lateral Raise —
The focus of this exercise is to target the shoulder muscles.
This is a point I mentioned above - I believe weight training should be
the focus of an exercise program for fat loss.
Now here's the cool thing about the abs crunch... depending on the type of abs crunch you do, you can shift
the focus of the exercise from the upper abs to the lower abs and even to the obliques!
Because of the way your abdominal muscle anatomy is set up, by making small variations in the way you do your crunches, you can shift
the focus of the exercise to different parts of your midsection.
However, even though you're doing a back and chest exercise, as I mentioned, that's NOT
the focus of the exercise.
Drive through with the heels of your feet, engaging your quads as
the focus of the exercise.
The focus of this exercise is on risk reduction or maximizing the return - risk trade - off.
