Start by exfoliating the skin in the shower with a body scrub or loofah.
Apply a thick, even amount of shaving gel over the area you plan to shave.
To shave your legs: Shave lightly from the ankles up
To shave underarms: Shave in all directions your hair grows
To shave the bikini area: Shave in the direction of the hair growth first; then you can go against the grain for a closer shave
Always moisturise your skin after every shave to minimise redness and irritation.
