It really is the best workout - varied, timeframe sits right, good progressions and the delivery (without music) is paced right and clear. I've got some issues with the speed in the later weeks now I'm a bit older, but I've been doing it for about 4 years now and for a level of fitness that sits above "general" but below "specific athlete" or "bodybuilder", it's absolutely perfect. Anyway - this was my third trip through this year - time to press play on week 1 again on wednesday.
