Personal record
Your best recorded result for a lift, tracked by weight, volume, or estimated 1RM.
// PROGRESS //
Your workout history should answer a useful question.
IronLedger turns completed sets into personal records, lift history, estimated one-rep max, and volume trends so you can judge whether the program is doing what you expected.
// THE SHORT ANSWER //
What does a strength progress tracker measure?
A strength progress tracker compares repeatable training signals over time. IronLedger focuses on completed load and reps, personal records, estimated 1RM, training volume, and exercise history—then keeps each number connected to the session that produced it.
// METRIC DEFINITIONS //
Know what each number actually means.
Estimated 1RM
An estimate of the maximum load you could lift once, calculated from a completed weight-and-rep set.
Training volume
The total load moved across completed sets, commonly calculated as weight × reps.
Exercise history
A chronological record of sets and sessions for the same exercise or variation.
// ESTIMATED 1RM //
Epley estimate
e1RM = weight × (1 + reps ÷ 30)
Estimated one-rep max is useful for comparing submaximal performances across sessions. It should be read as a trend, especially when rep ranges, exercise technique, or fatigue change.

Questions about the numbers.
How does IronLedger estimate one-rep max?
IronLedger uses the Epley estimate: weight × (1 + reps ÷ 30). It is an estimate for comparing training performances, not a guarantee of a true maximal lift.
What types of personal records are tracked?
IronLedger tracks supported records for weight, training volume, and estimated one-rep max.
What is training volume?
Training volume measures the amount of work completed. For weighted sets, a common calculation is load multiplied by repetitions, then summed across sets.
Can I see the history for one exercise?
Yes. Exercise history keeps previous sets connected to the exercise so you can compare load, reps, and effort over time.
Does more volume always mean better progress?
No. Volume is one signal. Exercise selection, intensity, proximity to failure, recovery, and program context also affect the meaning of a volume change.
