There are 8 officially recognized disciplines in freediving:

Constant Weight (CWT)

The freediver uses a monofin or bi-fins and the body’s own power to propel down and up again.
Here Guillaume Nery (France) dives to 109 m:

Constant Weight No Fins (CNF)

The freediver uses only arms and legs to perform the dive, swimming breaststroke down and back up.

See world record holder William Trubridge freediving the Arch in Dahab, Egypt:

Free Immersion (FIM)

The freediver dives under water without the use of propulsion equipment, but only by pulling on the rope during descent and ascent.
Andreas Güldner dives to 72 m (FIM):

Static apnea (STA)

The freediver holds his breath for as long as possible while laying face down in the water.
Eric van Riet Paap holds his breath for 7:33 in competition:
