Performance Strategies & Stumbles

In this Stumbles episode of Performance Strategies and Stumbles, I sit down with Stephanie Grubbs, Major League Assistant Strength & Conditioning Coach with the Houston Astros, to explore the early mistakes and leadership lessons that shaped her career.

Steph reflects on getting overly focused on outcome goals, the challenges of transitioning into leadership roles, and the importance of emotional awareness, communication, and mentorship in high-performance environments. We discuss why listening matters, how to navigate difficult conversations, and why building a strong support network is critical for long-term development.

A big thanks to our sponsor, The IUSCA, for this episode; they are also hosting the International Conference on Strength and Conditioning 2026, taking place at Leeds Beckett University on Friday, 5th June 2026. Get your tickets HERE

In this strategy episode of Performance Strategies and Stumbles, I’m joined by Stephanie Grubbs, Major League Assistant Strength & Conditioning Coach with the Houston Astros, to explore how microdosing strength training can be used effectively in elite team sport environments.

Steph shares practical frameworks for dividing volume into shorter, more frequent exposures, adapting training around travel and competition demands, and applying what she calls fluid microdosing to remain agile while maintaining structure. We discuss dose-response relationships, communication with athletes, and how to align strength training with the realities of modern sport.

You can also download a presentation resource she has shared with us (see the bottom of the show notes)!

In this Stumbles episode of Performance Strategies and Stumbles, I’m joined again by Michael Gerhardy to explore the mistakes that have shaped his practice as a sports scientist working in applied performance environments.

Michael reflects on early errors made in coaching, research, and sports science, including relying too heavily on statistical significance, misinterpreting data, and trying to analyse too many metrics at once. We discuss why concepts like P-values can be misleading without proper context, and why a “non-significant” finding can still provide valuable insight.

We also talk about the importance of quality over quantity in both training and monitoring, how data overload can undermine good decision-making, and why coaches and sports scientists must work closely to ensure analysis actually supports performance.

This episode is an honest conversation about learning through mistakes, developing better judgement, and focusing on meaningful metrics that inform real-world decisions.

In this episode of Performance Strategies and Stumbles, I’m joined by Michael Gerhardy, a sports scientist specialising in neuromuscular fatigue and applied workload monitoring.

Michael holds a PhD in Applied Sport Science, where his research focused on neuromuscular fatigue and concurrent training. It was during this PhD work that a key idea emerged — the value of running-specific testing to better understand fatigue and workload, rather than relying on generic or non-specific measures.

Michael is also the creator of RunUp Performance, a fatigue monitoring tool that uses raw IMU and GPS data to assess changes in running strategy associated with neuromuscular fatigue. His work helps teams move beyond simple workload totals and towards monitoring approaches that are task-specific, individualised, and practically meaningful.

In our conversation, we discuss the challenges of workload monitoring in sport, why population norms can be misleading, and how metrics such as ground contact time can help inform smarter training decisions. We also explore how excessive neuromuscular demand or poorly managed high-speed running can interfere with training adaptations.

This episode is about moving from data collection to better decision-making, and designing monitoring strategies that actually reflect the demands of running-based sports.

Dont forget we have the webinar with Michael that you can join by registering HERE to join us on the 10th February.

I am also holding 2x free mentoring sessions for anyone who hasn't experienced that type of work before, you can join us using links below:

Hope to see you there

In this Stumbles episode of Performance Strategies and Stumbles, I’m joined by Warren Bradley, founder of Hytro, to explore the mistakes and lessons that shaped his journey from working in professional sport to becoming an entrepreneur.

Warren reflects on his early career as a performance nutritionist, where not fully understanding hierarchy and environment led to avoidable challenges. He shares how saying yes too often, consulting across multiple teams, and constant travel resulted in overextension and burnout.

We then move into Warren’s transition into entrepreneurship — discussing early failures, the importance of market research, and how solving real problems in sport led to the creation of Hytro. Warren also speaks candidly about the role of self-care, delegation, and building a supportive team to create a sustainable working environment.

This is an honest conversation about ambition, resilience, and learning from mistakes — offering valuable insight for practitioners in sport and anyone considering a move into entrepreneurship.
