One of the thigns I hate about the new format is that we can't ask a coach what something means. I don't know what the above means. A "roll through" IM I would exepct to see for a 75 or 125 or something where you do 3 of 4, and each subsequent one, you progress (i.e. rep 1 is fly, back, breast; 2 is back, breast, free.....4 is free, fly, back), or you do a 50 and 3 25's. rolling through which stroke gets the 50 by rep. For a 100, I'm not sure. Especially given that you are also descending. Asked one of the Masters coaches at practice today, and he didn't know. FWIW, the workout is titled "100 IM's Descending," so I would doubt it would be 50, 25, 25, rolling through the stroke and skippng the free, but maybe? 2 of teh 4 IM reps are like this (also 4 on 1:40), the last set is 2 on 1:30 RACE. So again, those don't impress me that we are swimming the IM's non-free?
This is in the basic workout group, but it has 2 coaches, where they alternate easy/short workouts and longer/hard workouts. This is one of the harder ones. The author is "Larissa," who I see on some of the other categories. No idea if she posts here regularly. Again, stupid new format where we can't get in touch wtih them.
