Massage Therapist, Chiropractor, or Physical Therapist which one should you see?

When pain or an injury shows up, choosing the right professional isn't always obvious.
Massage therapists, physical therapists, and chiropractors each have different areas of expertise. Understanding those differences can help you make a more informed decision about your care.

At On Your Mark, we believe the starting point is the individual—your movement, goals, history, and specific needs.

Treat the individual—not just the symptom.

Getting more out of your side steps starts with the details.

The side step is a simple exercise often used for rehab, strength, and lower-body stability. But small changes in technique can help you better engage the muscles you're trying to train.

Mark shares one important tip for improving your side-step exercise and getting more from the gluteus medius, an important muscle for hip and pelvic stability.

Glute activation doesn't have to be complicated.

Side walks are a progression from side-lying leg lifts that help activate the gluteus medius and challenge hip stability.

Keep the shoulders level, push off the leg you're moving away from, and focus on controlled movement.

Try 1–2 sets of about 15 reps in each direction as part of your warm-up.

The goal is to maintain strong abdominal engagement while keeping the shoulders and scapula controlled throughout the movement.

It may look simple, but controlled ex*****on can make this variation surprisingly challenging.

▶️ Watch the demonstration and give it a try as part of your next core warm-up.

The Thoracic spine is the middle section of your spine, and it contributes to rotation, posture, and coordinated upper-body movement.

In this video, Mark demonstrates hands-on work with Vanessa while focusing on thoracic rotation and mobility.

Rather than simply forcing the body into a larger range of motion, Mark observes how the client moves and works with controlled positioning and rotation.

That's an important part of individualized bodywork:

You don't simply look at how much someone can move. You look at how they move.

Thoracic mobility can be relevant to many everyday and athletic movements that involve rotation, reaching, and changes in body position.

Mark's approach combines movement assessment with hands-on techniques to address the individual rather than applying the exact same approach to everyone.

▶️ Watch the demonstration to see how Mark assesses and works with thoracic movement.

Treat the individua not just the symptom.
