If three gym sessions a week is not happening, a smaller plan may still help. A narrative review of minimal-dose resistance training concluded that lower-volume programs, done with hard effort or spread into short bouts, can improve strength and function in younger and older adults.[1] The review does not set a magic number of sessions, so treat once a week as a place to start, not a finish line.
Why strength is the thing to protect
The review calls resistance training the only non-drug intervention known to consistently offset age-related declines in muscle mass, strength and power. It also notes that across the lifespan, strength and power fall up to eight times faster than muscle mass does, and they track more closely with functional problems and health risks.[1] That loss of muscle and strength is what sarcopenia describes.
Resistance training is also linked to lower all-cause and cancer mortality, and to a lower incidence of cardiovascular disease and hypertension, along with fewer symptoms of anxiety and depression.[1] Yet participation stays low, often because of time, difficulty or access to a gym.
What “minimal dose” means
The review describes two approaches that use less volume than standard guidelines:[1]
- Low-volume, high-load training: heavier loads and higher intensity, done less often.
- Resistance “exercise snacking”: lighter loads, done more often, with little or no equipment.
The authors add that these formats may cause less discomfort and more enjoyment than high-volume plans, which could help people stick with them.[1]
What this does not show
- It is a narrative review, which summarizes studies but does not pool them the way a systematic review does.
- The abstract does not name an exact weekly session count, so “once a week” is a practical starting point, not a researched target.
- Minimal-dose training is described as a way to preserve strength and function. It does not claim to match the results of a longer plan.
What to do with it
- Pick one session a week and protect it. A short one still counts.
- Choose a few moves that cover the big muscle groups: a squat or sit-to-stand, a hip hinge, a push, a pull and a loaded carry.
- Make the sets hard. The low-volume approach relies on effort, so stop when the last reps feel truly tough, not when the clock says so.
- On busy days, try the snack version: a few body-weight squats or wall push-ups between meetings.
- If you have joint pain, a heart condition or a long-term illness, talk to your clinician or a qualified trainer about how to adapt the moves.

Finding as used: resistance training is the only non-pharmacological intervention known to consistently improve and offset age-related declines in muscle mass, strength and power; declines in strength and power occur up to eight times faster than loss of muscle mass; resistance training is associated with reduced all-cause and cancer-related mortality, reduced incidence of cardiovascular disease and hypertension, and fewer symptoms of anxiety and depression; low-volume high-load training at lower frequencies, or lower-load training at higher frequencies with minimal equipment, can improve strength and functional ability; minimal-dose approaches may limit discomfort and lowered enjoyment, which are associated with higher training volumes. ↑︎
