I, typically use shower gel -- Caress raspberry scent.
My husband uses bar soap (Dial -- whatever is cheap at Sam's) and then occassionally will use HIS shower gel (Gilette) which he treats as though it's gold (uses it so seldom).
However, since I started working out, I will use bar soap for my workout shower. Reason: my arms are so sore that it's torture to reach up to the shower caddy and grab the shampoo, conditioner, and shower gel bottles. Usually, I'll reach for the shampoo and condiitoner because I need to wash my hair, but by the time I get to washing off my body -- I take the easy route and grab the bar soap which sits lower on a seprate soap dish.
