Most of us are not going to do an actual parachute jump just for fun or practice. There are busy jump operations at Longmont and Boulder where I often fly and most of those folks look like they are a different breed than most pilots.
Those sport jump operations use different chutes, the rectangular type that can do more, but take more input than our round emergency ones.

So how can you prepare as a pilot?
Expert chute packer and longtime sport jumper Alan Silver gives seminars at many EAA and warbird events and I'd make a point to see it. He does not say you have to be experienced to save your life with a chute in an emergency, just get yourself out however it takes and pull the ripcord.
He does emphasize mental practice and even real rehersal before flying. I know I have put a mattress pad on the ground and set in the cockpit and practiced all the way to jumping onto the pad.
Silver says time may be short if you have to get out at low altitude and practice can cut your exit time in half.
Alan mostly says, Canopy (open or off) Belts (off) Butt (out the door) and Pull ( the ripcord). At this point if the canopy opens as it almost always will you have saved your life, and should buy your chute packer a bottle of champagne and none of that screw top cheap stuff. Try to land into the wind with your feet together and knees slightly bent.
