LeisureSport?: going to the gym, and so forth; the implication is that it's for fun rather than out of necessity. SportS, in other words, but not as competetive.
LeisureLounging?: The kind of 'reclining-in-the-sun' type leisure, which implies going to sleep or a near-sleep lounging state. This is the type that's so different from ReCreation, which implies actually doing something to stave off boredom during less active times.
