How Physical Fitness Drives Performance in Professional Selling

It's easy to picture a successful salesperson as someone who masters negotiation, builds relationships, and closes deals. But as Keld Jensen points out, there’s an often-ignored, vital ingredient behind many of these successes: physical fitness.

Fitness sharpens both body and mind, building resilience, enhancing mental agility, and helping professionals process complex information and stress with greater clarity.

Self-discipline is a core value shared across high achievers; the discipline required to maintain a fitness routine often mirrors the rigor necessary for sales success.

Whether in the gym or at the negotiation table, consistency and commitment make the difference.

Managing Energy on the Road

For sales professionals, travel is a way of life—but it comes with its own set of health challenges. Keld, who spent 211 days away from home last year alone, shares firsthand how difficult it can be to maintain healthy habits amidst jet lag, poor food choices, and long hours.

To combat this, he relies on simple yet effective routines: regular exercise (favoring running for its minimal equipment), practicing intermittent fasting for mental clarity, and using conscious breathing exercises to lower stress.

Keld recommends fasting with fruit and tea for at least three to five days twice a year, especially before major creative projects.

This practice, he claims, not only cleanses the body but also dramatically improves mental sharpness—a critical asset for anyone in high-stakes sales or negotiation.

Building Daily Fitness Habits

Even amidst relentless travel, Keld commits to running three miles each morning—a habit chosen for its practicality and positive impact.

“It becomes the essential part of my day,” he notes, stressing the importance of movement, even if just a walk or a stretch, to break up long periods of inactivity.

His second key practice is taking “micro breaks” during work: stretching, walking, and resetting posture to help reset energy and counteract jet lag. Lastly, he emphasizes the protective power of sleep—something sales professionals often overlook.

Protecting sleep is the most important thing, as structured, sufficient rest equals sharper performance.

Turning Exercise Into a Competitive Advantage

Physical health is more than a “nice-to-have.” It’s central to managing stress, maintaining motivation, sustaining high performance, and making rational decisions.

Keld likens the effects of accumulated stress to “unbalanced concessions in a deal”—if left unchecked, both can lead to collapse. Treat fitness as your personal balancing tool.

On days when he skips his morning workout, Keld finds himself more stressed and less effective. Simply put: you can’t negotiate—or sell—well if you’re running on empty.

Strategies for Overcoming Lifestyle Challenges

Salespeople face real hurdles: long hours, irregular schedules, poor diet, and the ever-present pressure to perform. Keld admits
