🏁 Workout Effort Score Calculator

Turn time spent in each heart rate zone into one simple effort score. It is a quick way to compare a steady workout, a hard interval workout, and everything in between.

Formula: Effort score = Z1×1 + Z2×2 + Z3×3 + Z4×4 + Z5×5

Calculator

Low score = easy aerobic work | Mid score = solid steady session | High score = hard mixed or interval day

Why This Matters

A weighted effort score is a simple way to turn zone minutes into one number you can compare across workouts. It is especially handy when your week has a mix of easy, medium, and hard sessions.

It also helps explain why a short but hard workout can leave you more cooked than a longer easy one.

Put both together and you get a cleaner picture of how hard the week really was.

Tips

Frequently Asked Questions

Why weight Zone 5 higher?

Because time at the top end usually costs more recovery for the same minute count.

Does this replace workout load?

No. It is a simpler companion number, good for a fast read rather than a full training model.

Can I compare across sports?

Yes, as long as the zone definitions are consistent across those workouts.
