In the past, turning 40 often marked the end of an athlete’s prime. Yet, today, an increasing number of athletes are proving that peak performance can be achieved well into middle age. American ski racer Lindsey Vonn, who is 40, and rock climber Chris Sharma, 43, are just two examples of seasoned athletes continuing to push the limits of their disciplines.
Similarly, for everyday fitness enthusiasts, it’s still possible to achieve better health and fitness at 40 or beyond than you may have enjoyed in your 30s, provided that you adjust your approach. According to Dr. Elizabeth Matzkin, an orthopedic surgeon at Mass General Brigham Sports Medicine in Boston, success in fitness after 40 is all about making thoughtful adjustments. “It’s about effort and strategy,” Dr. Matzkin says. “You have to train differently.”
Avoiding the Pitfalls of Overtraining
As people transition from their 20s to their 40s, many mistakenly continue to use the same exercise regimens that served them well in their younger years. Dr. Miho Tanaka, a colleague of Dr. Matzkin at Mass General Brigham, highlights that this approach can lead to injury. “To build resilience in aging joints, most people need to completely change the way they exercise,” Dr. Tanaka explains.
The transition from youthful fitness to midlife training requires a different mindset. What worked in the past—intense workouts with little regard for warm-ups, cool-downs, or recovery—must be modified to ensure longevity in both performance and health. “It takes longer for your body to adapt to exercise as you age, especially if you’ve had a break from it,” says Dr. Tanaka. In addition, strength training, cardio, warm-ups, mobility exercises, and quality sleep become non-negotiable elements of fitness for individuals over 40.
The Physiological Challenges of Aging
One of the main reasons fitness becomes more challenging as you age is the natural decline in muscle mass that begins in your 30s. As you age, gaining muscle mass becomes a more laborious process, particularly when it comes to fast-twitch fibers responsible for explosive movements like sprinting. Dr. Tanaka explains that this is why many people experience peak performance in endurance events like marathons later in life, while fewer sprinters maintain their explosive speed past 40.
Additionally, tendons and ligaments—key components that support joints—become weaker and less flexible with age due to decreased collagen production. This contributes to a heightened risk of injury, particularly when engaging in high-impact activities.
Balancing High-Impact Exercise with Recovery
Despite these challenges, high-impact exercises such as running or jumping still play a crucial role in maintaining overall health, particularly for women facing perimenopause or menopause. Research indicates that weight-bearing, higher-impact activities stimulate bone growth, a vital consideration as bone density naturally declines with age.
However, as Dr. Tanaka advises, any new high-impact activity should be introduced gradually. For someone new to running, for example, it may take significantly longer to prepare for a race in your 40s than it would have at a younger age.
Building a Foundation for Success
Regardless of your starting point—whether you’re returning to fitness after a long hiatus or just beginning your journey at 50—building a solid foundation is essential.
Amy Schultz, co-founder of Contra Sports Club in Los Angeles, emphasizes that explosive movements like jumps and sprints should be avoided until you’ve established adequate muscle strength and stability. “If you don’t build a solid foundation first, you’re more likely to get injured,” she explains.
Schultz recommends committing to at least three workouts per week, with two active rest days, for a period of three to six months. The focus should initially be on improving cardiovascular endurance, building muscle mass, and enhancing core, hip, and shoulder stability. Gradually increasing workout intensity by 5 to 10 percent each month helps lay the groundwork for more specialized training as you progress.
For former athletes, the process may be quicker. “Muscle memory often kicks in, and motor skills from past sports can be regained within a few weeks,” Schultz adds.
Prioritizing Recovery and Adaptation
While intense workouts may have been effective in younger years, recovery takes on greater importance as you age. Recovery is not only necessary during the foundational phase but becomes even more crucial as intensity increases.
“You can’t go all-out with every workout,” says Mathias Sorensen, an exercise physiologist at the University of California, San Francisco. “Recovery becomes a critical component.” Recovery doesn’t necessarily mean additional rest days, but it does involve pacing your training. After an intense sprint session or heavy lifting, aim for three moderate training days followed by one light workout day, Sorensen advises. Light activities like yoga or low-intensity cardio can aid in recovery, as well as rotational exercises for golfers or mobility work for athletes engaged in other sports.
The Importance of Small Adjustments
In addition to modifying your workouts, there are smaller yet essential factors that influence fitness over 40, such as nutrition and sleep. Dr. Tanaka underscores the importance of warm-ups, cool-downs, and mobility exercises to maintain muscle flexibility and joint health. She also recommends increasing protein intake to support muscle repair and recovery.
Dietary considerations extend beyond protein. Limiting alcohol consumption is crucial, as alcohol can interfere with muscle recovery and overall performance. Consulting with a nutritionist can help tailor your diet to support your fitness goals, and a doctor might suggest supplements to promote joint health and bone density.
Equally important is ensuring quality sleep. “Sleep is when the body recovers,” says Sorensen. “You can follow the best fitness plan and diet, but without good sleep, peak performance is out of reach.” Prioritize rest and aim for at least seven to eight hours of quality sleep each night to facilitate recovery and optimize your fitness results.
By adjusting training methods, focusing on recovery, and making strategic lifestyle changes, achieving peak fitness after 40 is entirely within reach. Whether you’re a seasoned athlete or a newcomer to fitness, these changes can help you maintain strength, mobility, and performance well into your middle years and beyond.
