Mark Bell with Cynthia Monteleone Explains: Why Sprinting May Be the Missing Link to Living Fast, Strong, and Sharp Into Your 80s

Who’s in This Conversation

Mark Bell is a strength athlete, entrepreneur, and podcast host known for bridging the gap between elite performance and real-world longevity. Through The Power Project, Mark explores how strength, movement, and mindset translate into a longer, healthier life—not just bigger lifts.

Cynthia Monteleone is an elite sprint coach, former Division I track athlete, and the founder of Fast Over 40. She specializes in helping people preserve speed, power, and neurological function as they age. Cynthia has coached world-record-holding Masters athletes, Olympic-level competitors, and everyday adults who want to stay fast, strong, and mentally sharp well into later life. Her work blends sprint biomechanics, neuroscience, and longevity-focused training principles.

The Big Idea (That Most People Haven’t Heard)

Most people think longevity fitness means more walking, more jogging, more “zone 2.”
Cynthia Monteleone—elite sprint coach, former Division I athlete, and founder of Fast Over 40—argues that this advice may actually accelerate aging if it comes at the expense of speed, power, and neurological function.

Her central claim is simple but radical:

Aging isn’t just muscle loss—it’s loss of nerve speed. Sprinting trains the nervous system to stay young.

She doesn’t say this as a theory. She coaches:

• Athletes sprinting in their 60s, 70s, and 80s

• A father who started sprinting at 82

• World-record holders over age 60
  All without daily grinding or endless workouts

What Sprinting Does That Jogging Doesn’t

1. Sprinting Preserves Your “Fast Wiring”

As we age, we lose neuromuscular firing speed faster than we lose muscle mass. This is called dynapenia—and it’s why people feel “slow,” weak, or unstable even if they still lift weights.

• Jogging reinforces slow neural signaling

• Sprinting reinforces fast, coordinated firing

• Think fiber optic internet vs. dial-up

This neurological speed is what keeps you:

• From falling

• Able to react quickly

• Strong under sudden load (slips, trips, carrying kids or groceries)

2. Sprinting May Help Support Brain Cleanup

One of the more interesting (but still emerging) insights:
Regular exercise may support the brain’s waste-removal system, known as the glymphatic system.

This system depends on Aquaporin-4 (AQP4) channels, which help flush out metabolic debris linked to cognitive decline.

Translation: sprinting hasn’t been shown to directly “clean” the brain, but it may indirectly support the conditions—sleep quality, vascular health, and lower inflammation—that allow the brain to clean itself more effectively.

3. Sprinting Can Be Better for Hormones Than Endurance Cardio

Long endurance training, when overdone, or done under-fueled:

• Raises chronic cortisol

• Suppresses testosterone

• Can worsen perimenopausal symptoms in women

Sprinting:

• Boosts testosterone and growth hormone

• Improves insulin sensitivity

• Preserves lean muscle

This matters even more after 40, when hormones are already shifting.

4. Sprinting Makes You Smarter (Literally)

Sprinting increases BDNF (Brain-Derived Neurotrophic Factor) more than steady-state cardio.

BDNF acts like fertilizer for your brain:

• Improves learning

• Reduces anxiety and depression

• Supports long-term cognitive resilience

Many people feel this immediately: clarity, confidence, mood elevation after short sprint sessions.

Why “No Jogging” Is So Controversial (But Central)

Cynthia’s stance is firm: jogging trains your body to be slow.

• Long ground contact times

• Repetitive poor mechanics

• Gradual loss of fast-twitch fibers

Walking? Fine.
Sprinting? Essential.
Jogging? Often the worst of both worlds for aging bodies.

ACTIONABLE TAKEAWAYS (What to Do Differently)

✅ If You’re Over 40 and Active

• Sprint 2–3 days per week, not daily

• Full rest days matter—recovery keeps nerves sharp

• Keep sprint distances between 60–400 meters

✅ If You’re New or Deconditioned

Start here:

1. Bike or rower sprints (full-body, low impact)

2. Hill walking → hill jogging → short grass sprints

3. Sprint drills (wall marches, high-knee strikes)

Never jump straight into max-effort track sprints.

✅ Strength Train for Sprinting

Prioritize:

• Slow eccentrics (4–6 second lowers)

• Split squats (knees-over-toes style)

• RDLs

• Ankle stiffness work (jump rope, pogo jumps)

These build power safely, not recklessly.

✅ Eat for Neurotransmitters (Not Just Calories)

A standout insight most people miss:

• Morning: protein-rich meals support dopamine

• Evening: carbs support serotonin and sleep

• Avoid sugary breakfasts that spike and crash energy

Stable energy beats constant stimulation.

✅ Train Coordination, Not Just Muscles

Low-cost, high-return habits:

• Jump rope

• Rope flow

• Dancing

• Juggling (seriously—it trains prediction and balance)

These keep your nervous system young without stressing joints.

The Longevity Reframe

Sprinting isn’t about being the fastest person on the track.

It’s about:

• Keeping your nervous system sharp

• Maintaining confidence in movement

• Preserving power, balance, and brain health

Even an 82-year-old sprinting “slow” is sprinting fast enough to trigger the benefits.
