Personally, I don't think so. Certainly not unless you're training for a very tough, specific goal (e.g - marathon, ultra marathon, etc.)
Just find a way to motivate yourself and get yourself out of the door each day to do your session. As for planning sessions, I personally enjoy having a little look round the internet and getting ideas from that. You don't need a personal trainer to plan effective sessions for you. Provided you're willing to do a little bit of leg work (no pun intended!) and under go a little trial and error to find what works for you.
