Hi Tina,
Back again. The rotation I was referring to is Cathe's September 2003. It has a few more sprint workouts throughout the rotation. As well, I came across a post that she wrote in the Ask Cathe forum to answer a question. At the very end of the post she outlines a specific 56 minute interval running workout. I've pasted it here:
Cathe's post:
"Both Circuit Training and Interval Training are great.
I would do CT two three times per week and IT one time per week for three weeks.
Then I would do CT two times per week and IT two times per week (with three days between IT days, you can do other workouts in those three days just not another IT workout) for two weeks.
Keep alternating this pattern.
Now here is one more "magical" ingredient to bust through your plateau. If you do not run, throw this in the mix. Here is how. This workout will replace one of your planned IT workouts.
Also, before you throw it in the mix as an IT workout, do the following to acclimate your body first (so you don't get injured). You can do this acclimation workout right along with your scheduled CT and IT workouts. If you feel like it is too much then cut back on one of your CT workouts during the acclimation phase.
ACCLIMATION PHASE:
Week one and two: Walk at a fast pace for 20 minutes on non-consecutive days two times per week. Stretch your shins, calves, and thigh muscles thoroughly afterwards. This will help ward off shin splints.
Week three and four: Walk at a fast pace for 10 minutes and then go into a light jog for 10 minutes (walking fast at any time you can't continue to run). Do this two non-consecutive times per week. Stretch your shins, calves, and thigh muscles thoroughly afterwards.
After this period you are ready to do a "running IT" workout that will replace one of your originally planned IT workouts. This running IT workout goes like this: (total workout time, approx 56 minutes)
....5 minute normal to fast paced walk.
....5 minute fast paced walk.
....1 minute of a light jog immediately followed by one minute of a fast recovery walk (do this 1 to 1 cycle 6 times).
....15 second sprint (running as fast as you can for 15 seconds)immediately followed by a 45 second walk (do this 6 times)
....30 second sprint followed by a one minute fast recovery walk (do this 4 times)
... 5 minute light paced jog
....5 minute fast walk
....5 minute normal paced walk
....5 to 7 minute stretch really focusing on the shins (gently bend top of foot down in the direction of your arch), the calves (gently pulling the foot back toward the shins), and your classic hamstring, inner thigh, and quad stretch."
Hope this helps,
Sandra
