And a note on time: more is not more in strength training. A good workout can be done within 30 minutes, so clock watching isn’t necessary. In fact, a 2018 paper found that less than 45 minutes of exercise a week lead to “marked increases in strength and endurance”. The study, in Medicine and Science in Sport and Exercise, found that just three, 13-minute weekly sessions over an eight-week period led to “gains that are similar to that achieved with a substantially greater time commitment.” Researchers did note that longer training led to more muscle growth, but it’s important to remember that no high-intensity exercise over 90 minutes is really ever recommended – especially without food. - https://getpocket.com[..]gns-you-ve-trained-hard-enough-explained
