This post continues on from an older post about rest periods, and clarifies some of the potential nuances involved. In particular, while longer rest periods may be better, this needs to be considered in the context of a lot of other variables, and being proactive about managing your workouts based on total volume of training (rather than individual variables like rest periods) may be more meaningful overall. This also helps to explain why some lifters can get away with not following strict programming, training by feel, while still seeing great results.
