I'm a big proponent of training each body part at least once every 5 days - whether its in the form of a split or a full body workout. You just need to make sure recovery is in check. Nutrition is king, recovery is queen.
Doing 3 sets of various chest presses 3x per week is going to progressively overload the pecs to a greater degree than doing 9 sets of chest work in one session once per week.
Adjusting the exercises and volume/intensity take some trial and error. For example, deadlifting 3x a week is excessive and will probably result in over training. However; deadlifting once per week (very high CNS), squatting once per week (moderate to higher CNS), and doing a unilateral lower body movement once per week (say split squats or travelling lunges - low CNS) allows you to do the same work with a higher relative intensity than cramming everying into one session
