Returning to Sports as an Adult: Why It Keeps Falling Apart

Craig Smith February 19, 2026

Past Your Prime Podcast – Episode 52 Listen on:Spotify | Apple | Youtube Returning to sports as an adult often feels harder than it should. You finally get back into basketball, volleyball, running, or lifting. Things go well for a few weeks or months. Then something breaks down. A knee flares up. The calf tightens. The shoulder starts barking. Eventually you stop again. Then the cycle repeats. Most people assume this happens because they are getting older or because their body is fragile. But the reality is usually much simpler. Most people restart their sport without adjusting the standard they use for returning. They return using the same assumptions they had when they were 21. This episode of Past Your Prime breaks down why this happens and how to approach sports in a way that allows you to keep playing long-term instead of constantly restarting. The “Big Three” Problems With Returning To Sports As

Why Your Hamstrings Hurt After Stretching (and What’s Really Going On)

Craig Smith November 4, 2025

Stretching is supposed to make your hamstrings feel better—looser, lighter, more flexible. So why are you experiencing only temporary relief at best—and often feel even more sore after stretching? There’s a deep cultural belief in the power of stretching to reduce pain, improve mobility, and prevent injury. The support for those claims is, at best, inconsistent or non-existent. 1,2 If you’ve found this article, you’ve likely noticed a pattern yourself: every time you stretch your hamstrings, they get worse. At Smith Performance Center, we see this pattern constantly. The sensation of “tight” hamstrings is rarely about flexibility—even in those with limited motion. We hear people complain of tightness in tissue disorders that actually cause more motion than normal.  More often, it’s a protective signal that something is off in how your system is moving, processing information, or managing load. In this article, we’ll walk through what actually causes post-stretching soreness

From Pain to Progress: Building an Exercise Habit After Injury

Craig Smith January 13, 2025

A perfect time to build the exercise habit occurs when you overcome a painful injury. At Smith Performance Center (SPC), this happens during the “activity progression” phase after stabilizing symptoms. Unlike a standard exercise routine, activity progression focuses on managing and improving tissue capacity—your body’s ability to handle physical load without pain or injury. If these terms sound unfamiliar, don’t worry. The following signs indicate you may have skipped the fundamentals of activity progression: Why Delaying Exercise Is a Mistake Many individuals delay exercise until they feel completely better. However, this approach has drawbacks: Your Path at SPC At SPC, we’ve developed a clear plan to help you build fitness while overcoming an injury. Here’s how it works: 1. Your Home Plan: Manage Symptoms and Flare-Ups The biggest hurdle to starting exercise is handling symptom increases. If daily activities cause large spikes in pain, your exercise plan must be carefully

The 10 Strategy Mistakes of Repetitive Injury When Exercising

Craig Smith December 14, 2023

Do you want to get back to exercise but keep on getting hurt? The merry-go-round misery of repetitive injury when exercising is a common complaint at Smith Performance Center. When someone shows up, our physical therapists listen to a series of injuries that seem to occur every time they get into a workout routine. The exerciser finishes rehab and heads back to their respective sport. The first few days go well, but inevitably the same problem comes back. In our clients’ minds, their body has lost the ability to stay healthy. They believe age is driving the problem, or the joints are shot. They think the activity they choose to do is too vigorous and must be replaced.  These are not the problem.   The cycle of repetitive injury is a strategic mistake. Why Repetitive Injuries Keep Happening When You Exercise We believe in a process called the SPC Phases. A

The 7 Tissues to Consider When Progressing Activity After Physical Therapy

Craig Smith September 18, 2023

The Rehab Standard is an SPC concept that defines when a client has a higher exercise capacity than tissue capacity.   When your tissue capacity is lower than the exercise capacity, the focus of the workout is not how hard you worked out.  It is not how much you sweat or how good of a muscle burn you got. The focus is on the healing tissue and that is was not overloaded, irritated, or provoked.  A violation of the rehab standard can present as pain after the workout or the next day, even if there was no pain during the workout. The key is to focus on tissue capacity in the exercise selection, intensity, volume and the type of tissue injured. We want to look at this last one, the type of tissue injured, in relation to activity progression following an injury. The 7 Tissues to Consider When Progressing Activity Improving

The 5 Big Problems Facing Clients with Pain and Injury Who Want to Get Back to an Active Lifestyle

Craig Smith September 1, 2023

There are numerous problems facing people in living an active, healthy life, but it can be difficult to articulate the problem that needs to be solved. Let’s look at two people dealing with low back pain. One person bent over this morning to grab a pencil and now cannot stand up straight. The second person developed back pain years ago and stopped doing certain movements because of discomfort. The pain is still present daily and they use a combination of meds, massage, and chiropractic to keep big flares up away. Their problems are different despite both dealing with low back pain. The solutions are very different. The person who just hurt their back needs a diagnosis and a home plan targeting healing strategies and triggers. This may mean more frequent visits and removing anything that makes their symptoms worse. We will likely see this person a few times per week

The Injury Types That Are Mismanaged During Activity Progression

Craig Smith August 1, 2023

The rehab standard is simple; the limit to your exercise is not how hard you can work out, but rather working as hard as possible without going past your tissue capacity.  Our team sees violation of the rehab standard as the most frequent cause of failure during activity progression. A client will feel great and start to progress their workouts. There is no symptoms during the exercise and often no symptoms the same day, but the next day they feel horrible.  We know that in activity progression, you need to understand the type of tissue that is healing, the specific exercise, and volume. We also need to consider the type of injury: chronic, recurrent, and acute.  Chronic Injury For chronic, we mean is has been present for a long time. When you have a chronic injury or chronic pain, there are two issues: your exercise capacity is lower because it
