Resting heart rate is a simple but informative cardiovascular metric — lower is generally better, within the normal range. Most healthy adults sit between 60 and 80 bpm; trained athletes can run 40–60. Apple Watch reports daily resting heart rate, computed from the lowest sustained values during the day.
Weight loss, improved cardiorespiratory fitness, and reduced sympathetic tone all lower resting heart rate. GLP-1 protocols are associated with a modest RHR reduction in observational data, primarily as a consequence of the weight loss rather than a direct cardiac effect. Trial data shows a small heart rate increase on GLP-1s acutely (typically 2–5 bpm) that is offset over time by the weight-loss-driven decrease.
TRT and GH secretagogues do not have a strong RHR mechanism. Any improvement during those protocols is likely downstream of body composition and sleep changes.

GLP-1s acutely raise heart rate by 2–5 bpm via sympathetic activation. This effect is well-documented across the SUSTAIN and SURPASS trials and is generally not clinically significant in users without preexisting cardiovascular disease. Over 6–12 months, the weight-loss-driven RHR reduction typically dominates and net resting heart rate falls below baseline.
Most users see RHR start to fall once they’ve lost 5–10% of body weight, typically months 3–6 of a GLP-1 protocol. The drop continues as weight loss continues and stabilizes at the new lower body composition. Regimen shows RHR alongside your dose log so the trajectory is easy to read.
