An ongoing log of training and health data - strength, tonnage, body weight, and
whatever else gets tracked - updated automatically as new sessions come in. Two logging conventions
changed early on: dumbbells started being counted as a pair instead of one hand, and the gym
changed in July, swapping every stack for one with different increments. Everything below is
corrected for both.
01
The seam
Every session, bar height = tonnage lifted, colour = the muscle group that took
the most volume that day.
Diagonal-striped bars and hollow points mark sessions
logged away from the usual gym, on unfamiliar equipment — included in every total, but kept visually
distinct since the numbers aren't directly comparable to the home stack.
A small magenta dot above a bar marks a session logged
while feeling under the weather — included in every total, flagged for context only.
02
Overall strength
Every exercise normalised to its own starting point, then averaged. 100 = where you began.
Machine-agnostic, so it survives the gym change.
Across the log the index moves from to . The dip in
June reflects a five-week gap in training, not a loss of strength on any single lift.
03
By muscle group
Same index, split out. Sparkline shows the smoothed curve; the seam is where the gym changed.
Read Legs with caution. It has the fewest data points and the largest splice
correction, because almost every leg machine changed in July and early sessions on a new machine
improve fast for reasons that are not strength.
04
Muscle groups overlaid
Same baseline-100 index as the cards above, all seven groups on one axis. Toggle a chip to
show or hide its line.
05
Exercises overlaid
Any set of lifts, normalised to % change from each one's first logged session, so machines and
barbells with different starting loads sit on the same axis.
Pick one or more exercises above to
compare their progress.
06
Actual weights on the bar
No normalising. Best estimated 1RM per session, in kilograms, exactly as logged (after the
doubling fix).
Because the machines themselves changed in July, a step at the seam is the equipment
talking, not you. Compare within an era, not across it.
07
Volume
Tonnage per month, split by group. Bodyweight movements count at
assumed body mass.
Average load per set, by month

08
When you train
Start time, weekday, session length and the gaps between sessions.

Weight and reps per set
The shape of the work itself: how heavy each set was, and how many reps it ran for.
