Here's a great site that I've used in the past. Agree with @captbklee on push-ups, dips and planks, also things like squats and lunges and have some starter weights for things like rows (I use some gallon water containers, depending on the exercise will depend on how full they are!).

With the push ups if you can't start with the full body you have the option of using easier versions to work towards them. I've been doing his training and I've gone from being able to do none to kinda doing a few (I have a bit of weight to lose and strength to gain). scoobysworkshop.com/zero-to-100-pushups-for-complete-beginners/

Hope that's of some help and I'm just back on here so if anyone is looking for a MFP friend pls add me.
