With great difficulty. If you find a secret that lets you take a minimal or longer through a pounding beachbreak then tell me
Assuming you have a long beachbreak with no channel, there are a few tactics:
Wait for a few minutes at the waters edge (maybe combine that time with a few stretches if it is a cold day). Watch the waves and see where they break to, there are peaks and troughs. A peak is where the wave begins breaking, trough is where it finishes breaking. You want to paddle out in the troughs. Also look at where the other surfers paddle out.
When you paddle out at the trough, get to chest high and wait for a set of larger waves to come. After the set has finished you want to jump on your board and paddle hard to get out before the next set comes. One plus of a minmal is the phenomenal paddle speed, try to paddle around waves to avoid the breaking sections.
If you are unlucky enough to get caught in a set, jump off your board and push it through the waves. Your body will act like an anchor to stop you getting pushed back. If there is no one close to you, and a giant wave is going to break on you, as a last resort consider bailing your board and pencil diving (deep breath, push up off your board and dive vertically, feet first), you might want to hold your nose with one hand and leash with the other. This is usually avoids a tougher beating.
