For the first time in nearly two decades, the American College of Sports Medicine has updated its guidance on resistance training. At first glance, this appears to be a technical refinement of existing principles around strength, loading, and adaptation.
However, the more significant shift lies not in the physiology, but in the underlying philosophy. The updated guidance reflects a move away from highly prescriptive, “optimal” models of training, towards an approach that prioritises accessibility, flexibility, and long-term adherence. Consider a typical approach to resistance training:
A patient is prescribed a structured gym-based programme – 3 sets of 12 repetitions, across multiple exercises, performed 3/4 times per week.
On paper, this is optimal. In reality, it often fails. Time constraints, uncertainty around technique, and lack of feedback mean the programme is either performed inconsistently – or abandoned altogether.
Now compare that to a more flexible approach:
Short, guided exercise sessions performed at home. Real-time feedback to ensure movements are done correctly. Progression that adapts to pain, confidence, and daily routine.
The physiology is the same. The outcome is not.
Tiggy Corben, DocHQ Lead Physio: “We often see patients returning to the same exercises long after their rehabilitation should have progressed – not because the programme is wrong, but because they haven’t had the support to move forward.”
From Precision to Practicality
Traditional resistance training models have often emphasised precision: specific rep ranges, structured periodisation, and tightly controlled progression. While effective in controlled environments, these approaches do not always translate well into real-world settings, particularly for:
- Individuals managing musculoskeletal pain
- Time-constrained populations
- Those new to exercise
Exercise adherence rates in rehabilitation settings are often reported as low as 30%, with non-adherence reaching up to 50–70% in some MSK populations, significantly limiting outcomes. (https://www.physio-pedia.com/Adherence_to_Home_Exercise_Programs)
The updated guidance acknowledges a critical reality: The effectiveness of a programme is determined not only by its design, but by whether it is consistently followed.
Adherence as the Primary Outcome
Perhaps the most important implication of the updated guidance is the reframing of resistance training as a behaviour-driven intervention.While the physiological benefits are well established – including improvements in functional capacity, mental health, and chronic disease risk – these benefits are dependent on sustained engagement.
As such: Adherence should be considered a primary outcome, not a secondary consideration.
Supporting adherence requires more than initial instruction. It requires ongoing visibility, feedback, and the ability to intervene when engagement declines.
DocHQ addresses this through continuous monitoring of engagement, pain, and movement quality, enabling clinicians to identify risks early and adjust care accordingly. It also delivers behaviour-led nudges and reminders to keep patients on track. This shifts care from a reactive to a proactive model, boosting adherence up to 70-80%.
Programmes are built to be clinically appropriate, but also realistic and adaptable: ensuring they can be integrated into everyday life rather than competing with it.
The Role of Early Intervention and Minimum Effective Dose
The recognition that even low volumes of resistance training can deliver meaningful benefits represents a significant shift in how exercise is positioned within healthcare. The transition from inactivity to activity is consistently associated with the greatest improvements in health outcomes.
For MSK populations, this is particularly relevant. Many individuals present at a stage where high volumes or intensity are neither appropriatenor sustainable. By validating a minimum effective dose, the guidance supports:
- Earlier engagement
- Reduced intimidation for patients
- Greater inclusivity across populations
At DocHQ, this aligns closely with early intervention pathways operationalised through guided exercise programmes and supported by real-time feedback and physiotherapist oversight. Patients can perform movements in a range of settings, while clinicians retain confidence that effort is being applied appropriately and safely.
The updated guidance ultimately reinforces a shift that has been building across MSK care for some time: outcomes are not limited by what clinicians know, but by what patients are able to sustain. Resistance training is no longer just a set of principles to prescribe, but a behaviour to support over time.
For healthcare systems, employers, and digital providers, the focus must therefore move beyond optimisation towards implementation, designing care that is accessible, adaptable, and consistently followed. When adherence becomes the priority, meaningful, scalable improvements in MSK health follow.
