what it claims

It is possible to combine strength training and running without losing muscle mass, provided that the program, intensity, and nutrition are properly adapted.

holds up

Scientific research largely validates this approach, often referred to as concurrent training.

Scientific research largely validates this approach, often referred to as concurrent training. Meta-analyses (e.g., Wilson et al., 2012) confirm that while interference between the two disciplines exists, it is widely overestimated for the majority of practitioners. The key lies in managing recovery and energy availability, as highlighted by studies on the protein intake required to support these two types of exertion. It is true that an excessive volume of running can hinder maximum muscle growth if nutrition does not keep pace. Conversely, the risk of muscle loss is often linked to an unmanaged caloric deficit rather than running itself. Evidence shows that structured planning makes it possible to maintain, or even improve, overall physical condition without compromising muscle gains.

What the graded evidence says

Evidence: B

Linked to, not proven to cause.

Effect: all-cause mortality by combination of aerobic + muscle-strengthening activity — 1 h/week aerobic HR 0.85 and levelling to ~0.73 at 3 h/week; adding muscle-strengthening 1-2x/week conferred further risk reduction; lowest mortality in those meeting both guidelines
Measured on: US adults (416,420 and 500,705 in two national cohorts)

These are associations from observational cohorts, not proof of cause; healthier or more motivated people may do more of both. The specific percentages sometimes quoted for one activity vs another come from particular studies and shouldn't be treated as fixed.
