BodyPump!BodyPump and more BodyPump!!! I especially love the newer releases ie #50 onwards. In fact, I like most of Les Mill's workouts namely BodyBalance (aka BodyFlow), BodyStep and BodyCombat.
Other than Cathe, the home workouts I most enjoy are those with Jari Love (cant wait to get her new workouts), Tracie Long (TLT, Firm), Gin Miller (Simply Series & Bella Strength) and the most of the FitPrimes and KickButts. I also love The Hotpants Workout by Dan Karaty - its a dance workout.
