Exercise of The Week | Step Up/Down Rotating Away

👉 Builds internal rotation where you usually avoid it
👉 Integrates pronation and controlled knee valgus for stronger, safer squats

The legend that is has a ton of experience in Chiropractic and CrossFit so his opinion is shaped by many years in the trenches. I knew he’d be a perfect fit for the mentorship as he appreciates the practical reality of treatment VS training, the limitations and synergies.

@Wise terrible customer service. Tried to make a simple transfer from one of my personal accounts to another. Money hasn’t arrived 8 days later. Spent several hours talking to agents and no one can explain why it hasn’t turned up. Agents tell me I have submitted everything I need to on my side and that the escalation will get back to me in 2/3 days - what a joke.

For those new here or those that don’t know, here’s a little about me and how I came to be where I am today. I know all too well the frustration of injury getting in the way of training or sport, and that’s what’s led me down the path to really understand movement and the

Exercise of The Week | Medial Hip Stability

This drill does two things at once:

👉 Exposes hidden imbalances in the adductors and medial hip stabilisers

👉 Doubles as a brutally effective exercise to build strength where you’re weakest

When assessing a mobility restriction, we need to pay respect to WHEN the restriction manifests. Very often we see someone demonstrate amazing mobility on the couch or in an easy test but then that range shuts down in the movement that matters, so more detective work is

Most injury rehab stops at 75%.

The last 25% is the difference between “ok in daily life” and “confident under full sport conditions.”

A framework I use to close the gap (P-A-C-E):

Principles: respect the body as a system, not isolated parts.

Assessment: look for hidden dysfunctions like stiff ankles, poor big toe contact, or weak stabilisers.

Correction: prescribe drills that directly address those weak links.

Embed & Evolve: ingrain the new patterns under fatigue and competition.

David Shorunke applied this frameworks and returned to the CrossFit Games after 16 years of knee pain.

When considering “target muscles” we often neglect to think of the body as one system working together. Especially in big compound movements. Often the problem muscle is one we think of as the antagonist, pecs in pulling and lats in pushing are common patterns I see. Muscles

Training should make you injured less, not more, does yours?

When addressing imbalances, one mistake I see a lot is not going aggressive enough. We’re potentially undoing decades and millions of reps of a certain pattern so 60 instead of 20 split squats really isn’t that radical. From ep.131 beginners guide to

3 common movement mechanics issues I see in CrossFit athletes.

1. The Big Toe Connection

Many CrossFitters lose contact with their big toe during squats and Olympic lifts, often due to the old and outdated “knees out” cue. This shifts stability to the outside of the foot instead of the tripod (heel, pinky toe, big toe).

The result? Poor single-leg balance, weaker quad and glute recruitment, and extra strain on the knees and lower back. Over time, it limits mobility and robs you of strength gains.

2. Frontal Plane Hip Mechanics

CrossFit covers a lot of up-down and forward-back movements, but rarely side-to-side. Without training the frontal plane, the adductors and glute med stop working together properly.

This shows up in squats with knee wobbles and the lower back ends up overcompensating for missing hip stability. The end result is more pain, less power, and stalled progress.

3. Shoulder + Spine Side Bending

Most CrossFitters have almost no side bend in their thoracic spine and limited shoulder adduction overhead.

The shoulders need to work harder in overhead positions. Instead of a solid lockouts we get active holds, and the shoulders will burn out quickly.

__________

These 3 missing movement patterns are small hinges that swing big doors.

Once addressed you’ll notice fewer injuries, better mechanics, and surprising jumps in performance.

This is all covered in the latest episode of the Training Stimulus Podcast, where I deep dive into each of these movement issues.

No movement is wrong, BUT some are a better use of time than others. Nordics do train the hamstrings but the WAY that they train them is not that similar to how the hamstrings actually function in life/sport/gym. Maybe your key hamstring exercises should have more points of

It's all training.

Everything we do is conditioning our bodies.

How you spend your time, the positions, the postures, the movements, our body is always adapting towards them.

It's an incredible adaptation machine. In positive and negative directions.

Be conscious of the stimulus you're inputting.
