The more forward and lower position, the more strain on the low back especially. A shorter stem and a more upright position (steeper stem or riser bars) will alieviate this somewhat. The trade off is climbing efficiency. The more upright you are, the more difficult it is to effectively keep the front wheel down while climbing and the increased tendency to "loop out".
Here's a tip that may or may not help and has NOTHING to do with the bike.
Many cyclists have very strong hamstrings (back of upper leg) as a result, this muscle puts a lot of strain and stress on the low back. Make sure your buddy (and everyone) stretches out their hamstrings well before everyride. I actually do a stretching routine every morning to keep my low back loose. If I miss a day, I'm sore the whole day! You'd be surprised how much stretching your "hamsters" or "hammies" helps!
Plus, it's cheaper!
