What do you log?

[I_iz_a_fatass]

My written log has it all - date, time, lifts, what pre-workout (or middle workout) supplements, warm ups, and work sets, along with notes of how they went off the mean of "okay did them" for good and ill.

An 80-sheet 9.5 x 6 inch notebook works quite well for a yearly guide even if you're going every other day.

I currently log:

Program (HLM) and week number of cycle.
Start/End time of workout.
Average and peak heart rates.
Heart rate variability that day.
Calories burned per workout.
Exercises, sets, reps. Notes about cadence, ROM, etc.
Notes to change progression on exercises when needed.
Post-workout review (pick weights for next week's workout)
Reviews every three months of poundage and 1RM increases on all major lifts.
