In Experience Note #8, we broke down cardiovascular readiness, tracking Resting Heart Rate (RHR) and Intensity Minutes to lower biological Fitness Age.
The immediate question that follows is: How do you consistently log vigorous intensity minutes as you age without destroying your joints, hips, and spine?
The Aging Dilemma: Moving Beyond Running
As we age, our physiological capacity changes, and our orthopedic tolerance often changes faster.
In my initial manifesto on rejecting the “Standard Script,” I shared how much I loved running. But by age 51, chronic impact strain on my knees and lower back forced me to face reality: running was no longer serving my healthspan.
Losing a beloved routine is tough. Running is simple, accessible, and frictionless—you just lace up your shoes, throw on shorts, and step out the door. But if you are currently fighting chronic joint pain just to log pavement miles, celebrate the years you had with it and transition to low-impact, joint-friendly activities that protect your longevity.
Through extensive trial and error—testing kayaks, paddleboarding, swimming, cushioned treadmills and more—I refined a sustainable three-part cardio protocol that protects my back and knees while hitting every intensity target.
1. Low-Impact Aerobic Base: Road and Stationary Cycling
Over 15 years ago, my wife and I purchased hybrid bikes along with an indoor magnetic trainer stand for the winter months. About twelve years ago, I began riding once or twice weekly, and three years ago I stepped up to a dedicated road bike.
When I bought the road bike, the specialist helping me was an avid runner. We started chatting about running history, and she asked me with a smile:
“Do you know what they call runners as they get older?”
I asked what.
“Cyclists!”
She was right.
The Routine: During the Michigan warm months, I log one 10-to-12-mile, best-effort ride per week on dedicated asphalt trails. This builds a solid aerobic base to support my water skiing.
The Winter Standby: When the snow falls, that same 15-year-old indoor trainer stand hosts a weekly 35-to-40-minute stationary session, tracking heart rate and intensity minutes directly through my Garmin watch and chest strap.
2. Low-Impact Indoor HIIT: The Bowflex Max Trainer
To replace high-impact sprints, I integrated a Bowflex Max M7 Trainer. It combines the smooth pedal motion of an elliptical with the vertical climb of a stair stepper, eliminating ground reaction shock.
The Workout: With 20 levels of resistance, its signature session is a 14-minute High-Intensity Interval Training (HIIT) protocol consisting of 8 max-effort sprint intervals paired with 8 recovery intervals.
The Output: It burns roughly 200 calories in under 15 minutes, with nearly the entire block registered as vigorous intensity minutes.
Practical Tip: I run one to two of these sessions weekly during the seasonally colder months. While the M7 is no longer manufactured new, Bowflex produces modern equivalents, and lightly used models are widely available on the secondary market for a fraction of original retail.
3. Outdoor Functional HIIT: Slalom Course Water Skiing
My primary athletic passion is slalom course water skiing. I have skied recreationally since age 10, but I didn’t begin learning and running the formal slalom course until the summer I turned 60.
Breaking decade-old bad habits and learning tournament-level body mechanics in my sixties has been the single greatest driver of my overall conditioning. It provides the daily motivation to stay lean, preserve upper-body strength, and maintain cardiovascular endurance.
Beyond the camaraderie of being in the boat with training partners, slalom course skiing is quintessential High-Intensity Interval Training:
The Work Interval: Running a tournament slalom course requires skiing through an entry gate, cutting across the boat wake to clear six alternating buoys, and skiing through the exit gate. At a little over 30 MPH, a complete pass takes roughly 20 seconds of all-out physical effort, generating immense G-forces against the rope.
The Rest Interval: After a pass, you drop into the water while the boat circles around to position for the return run, providing 50 to 70 seconds of passive recovery.
The Volume: A full set consists of 6 to 8 successive passes—translating into a textbook 1:2.5 to 1:3 HIIT work-to-rest ratio.
Garmin recently introduced a dedicated “Water Ski” activity profile on compatible watches, which leverages GPS to track boat speed, course path, and heart rate intensity, letting you see how hard you pull across the wake by the maximum speeds you generate.
Key Takeaway
You do not need to pound the pavement to build world-class cardiovascular health. The key is finding joint-preserving activites that you genuinely love so consistency becomes automatic.
When your cardio routine connects to a sport or activity you are passionate about, training ceases to be a chore and becomes functional preparation for life.
Next week, in Experience Note #10: Strength Training to Defend and Build Muscle Mass as You Age, we’ll look at joint-friendly resistance training routines designed to build strength while keeping you injury-free.
Until then—here’s to building the best version of you!
