Can heart rate alone describe my strength sets?

No. When lifting, heart rate often stays lower than the effort. LeibFit therefore adds credit to strain for every completed set, on top of what heart rate already explains.

Can I do gym and running on the same day?

Yes. The cardio coach factors a strength day into its recommendation and keeps cardio easy and shorter on those days. Whether that suits you depends on your goal and how you feel, not just on a number.

Is every extra session worthwhile?

An app display alone cannot tell you that. Your plan, actual load and situation belong together.

Strength, cardio and recovery in one plan

When you combine strength training and cardio, your week is more than a list of single sessions. A run, heavy sets and your recovery belong in the same overview. In LeibFit, strength training, running and cycling sit together with sleep, recovery and strain in one app, and cardio adapts to your strength days.

Diagram with three perspectives on a training day: strength with sets, reps and weight; cardio with duration, heart-rate zone and bpm range; recovery, meaning what the night left you. Different details, not squeezed into one number.

Describe different sessions in their own terms

A strength session is described by exercises, sets, reps and weight. A run or ride by duration and heart-rate zone. These details are not interchangeable. A good overview therefore shows each session in its own terms instead of squeezing everything into a single daily number.

The day's strain still needs a common denominator. LeibFit uses time spent in higher heart-rate ranges. Because heart rate underestimates the effort of lifting, every completed set adds credit. How strain lowers readiness is explained in Readiness and training load are different.

One week, two counters

In LeibFit, strength and cardio days sit in the same weekly grid. They are counted separately, for example "Strength 2 of 3 · Cardio 1 of 2". That shows what is done and what is still ahead this week, without one session standing in for the other. Planned is not done: a session in the plan is not yet any load. Runs or rides you record with your watch are taken over from Apple Health and tick off the day.

When gym and cardio fall on the same day

The cardio coach factors the strength day into its recommendation:

Leg day: strength training is the main effort. Cardio complements it, shorter and easy in zone 2.
Other gym day: cardio stays deliberately easy and a little shorter.
Low recovery: a short, very easy session in zone 1.
Warning sign in your night values or strain already at the top of the day's target: the coach recommends rest.

The coach prefers to put the week's hard session on a day without gym. That keeps a heavy leg workout and intervals out of each other's way.

How recovery steers both sides

The morning's recovery applies to strength and cardio alike. When it is low, LeibFit trims the sets in your training plan and the cardio coach suggests a shorter, easy session. Readiness then shows how much of the day is left, for example before an evening run after a morning strength session.

Keep the start simple

Begin with what you already have: your values from Apple Health and the cardio coach, both free. The strength training plan, starting workouts and adapting them to your recovery are part of Premium. How to set it up is covered in Connect Apple Health and your training plan.
