I'm currently working as an accountant, I work out regularly, 6 times a week, and my gym sessions are around 1h, but I could reduce them to 30-40min if I'm focused. I'm about to start a PhD and I'm asked to dedicate 2.5 days per week to research, around 8 and a half hours per day. I'm currently looking forward to working as a teaching assistant, which I assume is around 20-30h per week, 4-6h per weekday. I have no problem in reducing my workout sessions to 3 days per week.
How do you find work-research-exercise balance?
