Record the retirement boundary, identify the replacement and start a new comparison series. Preserve old values under their original conventions rather than converting them to match the new machine.
Mark the last actual session on the old equipment
Find the latest saved workout you can confidently associate with the retired machine. Record its date and identifier in a companion transition note. If you do not know the exact removal date, say last recorded use instead of inventing a precise retirement date for the gym.
Keep earlier entries intact as records of their original conditions. A machine disappearing does not make its history useless, but it does limit direct numerical comparison with the replacement. Retain the old weight convention and setup key so you can still explain those sessions later.
Build the replacement reference from scratch
Identify the new manufacturer, model, units and adjustment system. Ask staff for instruction before treating a familiar exercise name as a familiar machine. Life Fitness documents different seat and start-position systems within its equipment range, illustrating why an old setting should not automatically transfer to a replacement.
Record the replacement setup you are taught in a new companion equipment card. Do not copy the old selector value as a starting instruction. This is an administrative handover, not a method for selecting a suitable load or deciding whether the replacement movement belongs in your programme.
Use an explicit boundary instead of a conversion factor
An illustrative transition note could read: old row R-1, last recorded use 8 October; replacement R-2, first recorded use 11 October. A result of 40 kg on R-1 and 25 kg on R-2 then remains two labelled machine observations. The invented figures are not an equivalence or a suggested replacement load.
Keep a stable movement-family reference if useful, but distinguish the equipment-specific series. Do not multiply all old entries by a guessed factor to make the graph continuous. A visible break is more honest than a seamless line based on an unsupported conversion.
Review consistency within the replacement series
Once you have actual sessions on the replacement, compare those with each other under the same setup. Check that the machine identity, load label, adjustment version and exercise definition match. Ask the programme author how they want to interpret the transition rather than demanding a new personal record immediately.
If the replacement changes the movement enough to require a revised programme instruction, preserve that revision separately from the equipment event. The machine change date and the programme revision date may differ. Keeping both prevents a later review from attributing every difference to a single cause.
Update the current routine without rewriting past visits
Nexal provides free custom workouts, manual logging and history on Android. Use the supported workflow to make your current routine reflect the replacement while keeping completed sessions understandable under their original labels. Retain the transition register in your own notes where extra metadata does not fit.
Install Nexal to test finding the last old-equipment result and first new-equipment result. Premium AI workout planning is optional if you need help organising a revised routine. Your immediate recording goal is a traceable handover that preserves past work and makes future comparisons specific to the new station.
Keep current routines and completed results clear through equipment changes.

Frequently asked questions
Should I delete history for a retired machine?
Preserve useful old records with their original equipment context. Mark the transition and compare replacement sessions within their own series.
Can I convert every old machine weight to the new one?
Do not invent an equivalence. Different equipment and label conventions can prevent a defensible direct conversion.
