Name the exercise you actually performed, preserve the reason for the change and compare each variation with its own earlier entries.
Establish which alternatives are suitable beforehand
Ask the person who designed your routine which alternatives are appropriate when equipment is unavailable. Keep the agreed list alongside the programme. Similar-looking movements are not automatically interchangeable, and a shared muscle-group label does not tell you whether an alternative fits your instructions or circumstances.
For a practical planning example, your coach might provide a preferred movement and an approved alternative for the same session slot. Record both names in the planning reference, but only log the one you perform. If pain is the reason for stopping, seek appropriate advice rather than treating equipment substitution as an injury assessment.
Use the performed variation as the history identity
If the plan says machine press and you perform a coach-approved dumbbell variation, leave the completed record under the dumbbell variation. Keeping the old exercise name while changing only the load makes the history look continuous when the equipment has changed. That confusion carries into every later comparison.
Include meaningful distinctions such as seated versus standing, supported versus unsupported, or the specific machine when relevant. Avoid adding a new exercise identity for trivial spelling changes. The useful rule is that the name should distinguish a setup change that would matter when reconstructing the session.
Start a separate baseline for each substitute
Imagine the preferred machine entry reads a marked 30 kg and the replacement uses 10 kg dumbbells per hand. Neither multiplying the dumbbells nor matching the machine label produces a reliable conversion between the exercises. Keep both resistance conventions intact and review each against its own previous use.
If this is your first time logging the approved substitute, it is a baseline entry. Do not manufacture a previous result from the preferred movement. At a later session you can compare the same substitute, equipment and instructions, while still recognising that its placement in the session may affect the context.
| Visit | Performed movement | Comparison reference |
|---|---|---|
| 1 | Preferred machine variation | Earlier entries on that machine |
| 2 | Approved dumbbell variation | First entry for this variation |
| 3 | Preferred machine variation | Visit 1 and earlier matching entries |
No load equivalence or exercise suitability is implied by this example.
Keep temporary changes distinct from programme revisions
Write a short reason in a companion record when necessary: preferred machine occupied, approved alternative used once. That is different from a permanent programme revision starting on a given date. Without the reason, the next visit may accidentally repeat a one-off change as though the whole programme had been rewritten.
After several visits, review which substitutions recur. If the same station is unavailable every Tuesday, bring that concrete pattern to your coach. They can help decide whether a permanent change is appropriate. Your contribution is the attendance and equipment evidence, rather than a guess that the alternative must be better.
Use custom workouts as a manual record of decisions
Nexal on Android offers free custom workouts, manual workout logging and history. Use those features to record an existing routine and the actual exercises completed. Keep the approved alternatives list separately if you need context beyond the available workout fields. This workflow does not rely on an automatic substitution engine.
Before the next visit, check the original programme, any dated revisions and the last matching entry. That brief check prevents a temporary equipment workaround becoming an unexplained permanent change. Premium AI planning is optional when you want help organising a routine, but generated suggestions still require review for suitability.

Frequently asked questions
Should substitutes share one exercise history?
Keep meaningfully different variations distinguishable and compare each with matching earlier entries. A shared informal name does not establish equivalent resistance.
Can I swap an exercise because it hurts?
Stop and seek appropriate guidance for pain or concerning symptoms. This record-keeping method does not determine which replacement is safe for you.
