How to Avoid Gaining Weight During the Holidays
Dr. Cindy Dallow PhD, RD 11/3/2025 One of the most common questions I get as a dietitian is, “How can I prevent gaining weight during the holidays?” Let’s be honest, the stretch between Halloween and New Year’s can be tough, even for the most dedicated fitness enthusiasts. Candy bowls at work, big family dinners, endless parties, and travel all make it easy to consume extra calories and skip workouts. Research shows that the average adult gains about two pounds during this ti

SkiMo Success: Training, Resilience, and the Role of Coaching in Injury Prevention
By: Duncan Koehn MS Ski mountaineering (AKA Skimo) is one of the fastest growing winter sports in the world. With more resorts opening their slopes for uphill access and its official inclusion in the 2026 Olympics, participation is skyrocketing.

VO₂ Testing: The Healthspan Metric Every Mountain Dweller and Athlete Should Know
Let’s get a few of the major questions out of the way right off the bat: What is VO₂? • VO₂ is the volume of oxygen consumption. VO₂ max = your aerobic engine size. Bigger engine, bigger buffer for stress, sport, and life. Why is VO₂ important? • Higher VO₂ max = longer, healthier life, independent of other risk factors. The least-fit group has ~4× higher mortality risk than the fittest peers. What does a VO₂ test provide you with? • A number that is comparable to others wi

How Dry Needling is Shaping Smarter Clinical Decisions: Referral Patterns

Enter dry needling: a targeted, evidence-based intervention that’s rapidly becoming a mainstay in sports rehab and physical therapy.

Chronic Spine Pain Doesn't Need an Injection: The 2025 BMJ Guideline Just Torched Common Spine Treatments (and Why PT Still Wins)
Let’s get one thing straight: if you’ve been told that chronic spine pain means you need an injection, a nerve burn, or a steroid cocktail to “get your life back,” you’ve been sold a shortcut with no finish line. The 2025 BMJ Clinical Practice Guideline just dropped a bombshell on the spine world, and it’s one we’ve been preaching at Summit Sports Lab for years: Most commonly used interventional procedures for chronic axial and radicular spine pain have little to no lasting

Why Gait Analysis Might Be the Most Underrated Weapon Against Running Injuries
Let’s be real for a second, if you’re logging miles, you’re loading joints. And if you’re loading joints with imperfect mechanics, you’re playing the long game of Russian roulette with your knees, ankles, hips, and everything in between. If your mechanics suck, you're headed for injury. Overuse injuries plague 30–80% of distance runners annually. That’s right. Even the weekend warriors who just “jog for fun” aren’t immune. If you’re running without understanding how your body
