How many push-ups/crunches etc do I have to do to get abs and biceps I can only do 5 good push ups

Difference between normal and abnormal tissue is much clearer on mri than on ct and mri much suitable to view soft tissues

If it's a smaller child or infant, place one on the middle of the chest and on the child's back. (if it is a bigger child with enough room for two, place one on the upper right/your left of the chest, and one on the lower left/your right) the pads should never touch each other.
