Sly and the family Stallone are vacationing in Saint-Tropez to celebrate his recent 72nd birthday. While he was playing Jack on Tuesday ... Jennifer and their daughters, Sophia and Sistine, were on paddle boards, attempting what looks like some yoga positions.
The fam's already enjoyed some top-deck time -- sunbathing in their bathing suits -- and now they're looking to enjoy the Mediterranean waters.
If anyone's got it better than Sly ... nevermind. Nobody does.
