Because deliberate practice requires your full attention, with maximal mental and/or physical effort, it can only be sustained for a short period of time. Laboratory studies of extended practice have capped the optimal time at one hour per day, three to five days a week, and real-life studies have seen reduced benefits when practice sessions exceed two hours.
This level of intensity and concentration makes recovery time important. Whatever type of leisure activity or relaxation you choose, it’s important to offset the intense effort of deliberate practice to avoid mental or physical fatigue.
