Resistance training improves BMI among youth and may improve blood pressure, according to a review study by Spanish and American researchers in the International Journal of Environmental Research and Public Health (2020; 17 [21]). The review included eight studies with a total of 571 participants ages 8–18. Analysis is difficult due to wide variability in study protocols (i.e, intensity, volume, frequency and duration of resistance training), so more research is needed.
