I saw this website just recently, drawabox.com, it's a whole course that deals only with form. That'd be a great place to work through. Also your preston blair book, just practice copying those drawings and making your own is a good exercise - aim for accuracy!
About rendering, I'm sure you are familiar with all the lighting terminologies? passive / active highlight, core shadow, shadow, reflected light, cast shadow, occlusion shadow. A good exercise is to do your still lifes, but try to ignore the colours and draw them as volumes and observe and draw where those different light / shadow parts are. Proko has some great stuff on shading, so does Sycra, check those too if it's a bit hazy.
