After listening to Coach on the podcast mention we should do a workout in 20 minutes I suspected I was taking too many breaks. I can usually do F7 in 60 minutes so I must be have been resting too much.
Today I made a big effort to not rest between the work set and iMs. I also moved quickly from exercise to exercise with a quick drink of water. I got through the whole workout in 40 minutes with no resting. It was obviously a lot harder and I could not do as many reps, especially on the last sets. I will have to drop back a mini cycle for most exercises. This was week 3 in my cycle so there I should be able to keep this workload up regardless of the week.
I think I was turning Foundation into more of a strength workout and missing out on the conditioning aspect.
The less rest means I will probably progress slower due to conditioning and strength endurance limitations. I think this will line up better with my connective tissue adaption.
