Most runners know that to get faster, their workouts have to gradually get more difficult over the course of a training cycle. This concept is called progression and helps runners achieve new levels of fitness as their bodies adapt to higher workloads.
But many runners don’t follow the principle of progression for their strength workouts. They do the same core session year after year, or always stick to a similar series of exercises in the gym. Running the same workouts at the same pace isn’t the best long-term strategy to improve and get faster, so why do many runners never implement progression in their strength workouts?
After coaching hundreds of runners, my experience is that most runners simply don’t care that much. We want to run, not lift weights! But overlooking this crucial aspect of your training is leaving extra speed on the table and increasing your risk of overuse injuries.
Instead of letting your strength stagnate, let’s discuss the goals of strength work and how to properly implement progression in the gym—and enjoy it more in the process as you feel your growing strength.
Because many runners misunderstand why they should be lifting weights, they do the wrong things. The most common mistake is lifting for endurance by doing high reps with short recovery intervals. Runners gain endurance on the road, trail and track, and don’t need to spend their time in the gym building more.
Instead, runners should lift for strength—or the ability to lift more weight. By getting stronger, runners will improve their efficiency, muscle fiber recruitment and power.
These adaptations have distinct benefits for distance runners, allowing them to impart more force into the ground and run faster. The hormonal response of lifting heavy, including increased testosterone and human growth hormone production, can improve recovery and ultimately the ability to tolerate higher workloads.

Lift for strength by following these rules:
Following these practices will ensure you’re maximizing strength gains from each workout.
If you’re new to strength training, it’s not a smart idea to jump into a series of heavy dead lifts on day one. Instead, follow the first rule of progression: start general.
General strength forms the foundation that allows runners to progress to more advanced lifts in the gym. Start with relatively simple core exercises like planks, oblique twists and side planks. Exercises performed on the ground in a prone or supine position are more general than those performed standing up, since running is a standing activity.

After 3–5 weeks of consistent core workouts, you’re ready to progress to more advanced exercises. A valuable way to bridge the transition from bodyweight core exercises to difficult gym workouts is by starting with a medicine ball workout.
Medicine balls are a helpful strength tool that can be used as the next logical step after bodyweight exercises become too easy. The same exercises you’ll soon be doing in the gym—like squats, dead lifts, and lunges—can be done with a medicine ball.
After another 3-5 weeks of combining general strength and medicine ball workouts, you can progress to more advanced lifts in the gym.
Now that we know to start general with bodyweight exercises, move to medicine ball workouts and finally transition to weight lifting in the gym, we can fine-tune our approach to strength training with these three rules:
