Jefferson Curls: Benefits And Stronger, More Flexible You

I have been working on my overall flexibility. It seems like it is something you just have to concentrate on as you age. Several years ago I head a Tim Ferriss podcast with former Olympic gymnastic coach and founder of Gymnastic Bodies, Christopher Sommer. One of the core parts of his routine was what he called “Jefferson Curls”. Since then I try and do Jefferson Curls on at least a weekly basis and I really try and do them every day to strengthen my lower back, improve hamstring flexibility, and have a spine that would make Gumby green with envy. I also sprinkle in other flexibility exercises like kitchen sink stretches, yoga flows, and dead hangs.

In this post, I am going to go give you a little of the history, benefits, proper technique, and my experience with incorporating it into my routine.

The Curly Origins: A Brief History

As with many great things in life, the Jefferson Curl has humble beginnings. This exercise was named after the third U.S. President, Thomas Jefferson, who supposedly used it to keep his wig looking fabulous (just kidding!). The Jefferson Curl (and Jefferson Lift), owes its moniker to the circus strongman, Charles Jefferson. He traveled and performed with Barnum and later with Barnum & Bailey. and was known for chain breaking and lifting extremely heavy weights.

Over the years, this unique exercise has been embraced by gymnasts, weightlifters, and weekend warrior types like us. Many fitness aficionados swear by its benefits. It may feel awkward initially, but you will eventually get the hang of it.

Jefferson Curl Benefits

Jefferson Curls have a lot of benefits. I have never been very flexible and I can tell the difference (in a bad way) if I string a couple of days together where I don’t do these. Here’s what you can expect when you incorporate them into your workout routine:

  1. Strengthens lower back muscles: These curls are like a warm embrace for your lower back, helping to build strength and resilience.
  2. Enhances hamstring flexibility: Say goodbye to those stiff-as-a-board legs, because these curls will have you feeling like a supple, bendy straw. There is a version of the Jefferson Curl that the knees over toes guy, Ben Patrick, uses for this reason.
  3. Improves core stability: Jefferson Curls aren’t just about the back—they’ll also challenge your core, ensuring your torso is as stable as a well-constructed Jenga tower.
  4. Increases spinal mobility: You might not think about your spine often, but it’s time to give it some love.
  5. Reduces the risk of injury: Let’s face it—no one wants to be sidelined due to a workout injury. By improving your flexibility and strength, Jefferson Curls can help keep you in the game.
  6. Promotes overall functional fitness: Like the cherry on top of a sundae, these curls bring all the benefits together to make you a more capable, flexible, and functional human being.

Proper Technique for Jefferson Curls

As with any exercise, mastering the Jefferson Curl is all about nailing the technique. Follow these steps to ensure you’re bending over backward (and forward) in style:

  1. Correct starting position: Stand tall with your feet hip-width apart, holding a lightweight (such as a kettlebell or dumbbell) in both hands. If you’re new to this exercise, you may even want to start without any weight to get a feel for the movement.
  2. Lowering phase: Take a deep breath in, and then slowly exhale as you hinge at the hips, allowing the weight to lower toward the ground. Keep your knees straight but not locked, and let your head and upper back round forward naturally. The goal is to feel a gentle stretch in your hamstrings without any pain or discomfort.
  3. Lifting phase: Inhale and engage your core as you slowly reverse the movement, stacking one vertebra at a time until you’re standing tall again. Keep the weight close to your body throughout the entire movement.
  4. Breathing technique: Remember to breathe! Exhale during the lowering phase and inhale during the lifting phase. Proper breathing helps maintain stability and control during the exercise.
