Strength Training For Runners And Endurance Athletes

Why endurance athletes often skip strength training

A common assumption that lifting will add unwanted bulk or interfere with running-specific adaptation — a concern that's largely unfounded for the moderate strength training volumes that actually benefit endurance performance.

The performance benefits

Stronger muscles and tendons improve running economy (using less energy at a given pace) and provide better shock absorption, which reduces injury risk — one of the biggest limiters of consistent training for many runners.

What kind of strength training actually helps

Lower-rep, moderate-to-heavy compound lifts (squats, deadlifts, lunges) two to three times a week, alongside some single-leg and core-focused work, tend to translate best to running performance without excessive added mass.

Fitting it around a running schedule

Strength sessions on easy running days, or separated from hard running sessions by at least a few hours, minimizes interference between the two types of training while still capturing the benefits of both.
