They can be if that's what you'd like, and it's appropriate for your individual circumstances however, the exercises I set vary a lot for each person. My focus is agreeing with you what amount of time you have to strength train each week and how it can work best for your schedule. Often it's 15-20 minutes, 3-4 days per week, mixing body weight and resistance band exercises, or the use of more equipment for those who have access to it.
