Nothing makes a workout trendier than a political endorsement. Special thanks to vice-presidential candidate Paul Ryan for popularizing the killer P90X workout series, which he credits for his 6%–8% body fat. Ryan — sometimes joined by P90X creator Tony Horton — even leads P90X sweat sessions with fellow Hill staffers. For those without passes to the Capitol, the home-fitness package by Beach Body includes 12 workout DVDs and nutritional guides. The workout, which doesn’t require any equipment but relies on using the body’s own weight as a tool, stretches over 90 days of plyometric exercises, weight training and even yoga. The mash-up of different ways to work muscles is intentional and meant to keep users from falling into fitness ruts. If followed religiously, Horton claims, the program can transform bodies from flabby to fabulous.
