In this edition:

  • Why concentric hamstring strength matters

  • How pros address lingering high hamstring strain with the Half-Kneeling Hammy Pull

  • The ultimate hamstring builder: Nordic Hamstring Curls

Let’s dive into it.

Running publications often focus almost exclusively on eccentric hamstring work: lowering the leg in single-leg deadlifts. We discussed this last week. BUT… what about the concentric phase?

2 weeks ago we talked about the single leg hamstring curl. This is a great start for injury prevention. BUT what happens when you decide to rip that interval?!

Believe it or not your hamstrings play a huge role in generating power for speed! Single leg curls are not enough to handle the demand.

Enter the Nordic Hamstring Curls - scroll to section 3 for the exercise!

High hamstring strain and lingering tightness is surprisingly common — even in elite athletes. We have been blown away with the effectiveness!

One of the most effective solutions we’ve found: the Half-Kneeling Hamstring Curl.

  • Start in a half-kneeling stance

  • Actively pull the back leg down using your hamstrings

  • Maintain spinal neutrality and hips square

  • Add resistance with a band or cable as you progress

We’ll include this in our deep dive and Instagram later this week, so keep an eye out.🧐 Yup - a little plug for you to check out our IG 😂.

The Nordic Curl remains the gold standard for hamstring strength, combining both eccentric and concentric work.

What it works:

  • Hamstrings (distal and proximal)

  • Glutes and posterior chain coordination

  • Core stabilization

Why it matters:

  • Builds resilience for sprinting, long runs, and accelerations

  • Trains hamstrings through the full range of motion

  • Reduces risk of recurrent strains

How to train it:

  • Start: 2-3 sets of 4-6 slow, controlled reps

  • Progress: 6-10 reps with added tempo or resistance

  • Focus: Hips neutral, extend from knees first, control descent, and drive back up

Key takeaway: Combine concentric-driven exercises like the Half-Kneeling Hammy Pull with Nordic Curls for complete hamstring development — stronger, faster, and less injury-prone - Stay tuned for the deep dive at the end of the month!
