I’m starting the strength phase (week 6). So far so good, but I’ve read and re-read the PDF several times and can’t figure out the sets and reps are supposed to be for this phase. It says “2 days per week and 4 sets of variable reps. See resistance program spreadsheet for sets, reps and weights for each lift. Make a note that the first 3 strength workouts labeled 1 - 3 are different than those labeled 4 – 6, for a total of 2 weeks.”

(a) there are only 4 lifting workouts in the 2-week strength phase (not 6). What am I missing?

(b) the spreadsheet shows different weights for “Strength (1-2)” and “Strength (3-4)”. I’m not sure what the difference is there.

(c) Lastly, I’m not sure what “variable” reps are.

Looking at my schedule I have Strength 1, 2 and 2 x Strength 3 workout before moving on to power.
Now looking at the resistance program spreadsheet this is what I see - Strength (1 & 2) with 4 session and Strength (3-4) with 4 sessions.

Session 1, 4 sets x 6 redos
Sessions 2, 4 sets x 6 reps
Session 3, 1st set x 8 reps
2nd set - 6 reps
3rd set x 4 reps
4th set x 2 reps
Session 4 same as session 3

It appears the spreadsheet has since been modified since my original download.
I opened the spreadsheet link yesterday from my daily workout reminder from TP and it’s different than the one I saved & used when I first began the program.
I begin strength session 1 on Monday.
