Strength

Lifting that doesn't lie about your fatigue.

A heavy squat session leaves you tired in a way no TSS number describes. Helios counts it as what it is, and the coach sees it before it schedules Thursday's intervals.

87cited strength workouts and 7 plans, scored as Session-RPE.

What your coach sees

What a strength coach needs. Exactly.

Session-RPE, kept honest

Strength load is your CR-10 rating times the minutes, and it stays that way. Helios deliberately refuses to convert it into a TSS-equivalent, because a fabricated endurance number would corrupt the one curve your training decisions actually rest on.

Thirty-eight sessions and an exercise library

Programmes for the athlete who lifts to ride or run better, and for the athlete who lifts: sets, reps, tempo and load prescriptions with sources on every entry, plus prehab work that attaches to a session without counting as one.

Monotony and strain, not just volume

The weekly review reports Foster's monotony and strain alongside the totals, so a week where every day looked identical reads differently from a week with real hard-easy separation — which is the difference that gets people hurt.

No invented numbers.

Load is session-RPE — your rating times the minutes. Rate a session and it counts; leave it unrated with nothing measurable to fall back on and Helios says so rather than inventing a number.
