@chbartist sir!
The most important aspect to design any work out is time division.Today our brain is working like a machine but it is not a machine, so it also needs to be refreshed to get energy .The biggest advantage of working according to the time division is that we neither feel mental fatigue nor feel boredom towards work. After an hour and 40 minutes work, the 20-minute interval is enough to refresh the brain and recover the energy. Thank you for sharing a new idea every day.
