Poisonally, I'm OK with no ab/core work. I've got a double VCR so I've already made a tape of most of your ab routines. Plus I'd like to spend that extra time on legs and I only have about an hour to work out max.
One-half standing and floor work sound great. And, of course, calf work would be appreciated. I'm nearly recovered from Plantar Faciitis in my right foot, and I find the calf work on the 2-by-4 in SLA helps enormously.
Oh! Almost forgot! Would it be possible to do step-ups but in slower motion, please -- especially going down. That way I can use better control and isolate the muscles better.
Oh, and may I also add that I love the pace of SLA. This is gonna sound silly, but I find SLA pays "homage" to the body, or in other words, respects it, by taking a rest between sets. I find I don't dread it as much as some other gruelling leg tapes in my collection (need I mention Leaner (Meaner) Legs?)
Thanks for asking! Just wanted to add that everything you do is superb!
