Reastie I can't help with the workouts as I only know about the T25 or 21df/21dfx ones as those are the only ones I do! Although if you want a leg workout, 21df Barre Legs is good - it doesn't involve weights and is mainly squats/lunges/leg lifts of different types and the pattern is 20 full moves, 20 small pulses then a 30-second hold - you repeat this for each different move. It is quite basic but effective.
PurpleI am with you on the starving front - I did Pilates Fix at 5.15 this morning then had a Tracker bar at 10.00, went into a meeting, came out at 11.30 and thought I would have lunch then got ambushed by 2 other people who talked to me for an hour...I could literally have eaten my hand by that point 
The new Shaun T workout - it is a Shaun T week (12th June I think) and he is releasing a new workout each day for 7 days. No clues yet on what type/length of each one but it covers cardio, abs, strength. Hopefully they will land on the secret site shortly after [happy]
Did I mention that I have started doing some Core de Force workouts? They are fab - has anyone else done them? I am just sticking to the Shred and Speed ones at the moment (depending on how much time I have) maybe once or twice a week when I want a cardio workout. I love the format and it is very similar to bodycombat classes which I miss so much! So I now have a weird hybrid of T25, 21df, 21dfx and Core de force
Keeps it interesting though!
