if you want muscle strains then go for it. It might reduce max presses because the muscle isn't as playable, but it doesn't promote mire growth. If you are talking on the terms of growth then ton need to research growth, not max Press. You have to stretch the muscles completely through its entire range to include all muscle fibers in the group. This is the reason for feeling a good stretch on fly or why you stand in a block when doing calf raises to stretch the muscle throughout its full range.
I've been a competitive athlete since 7 years old. USS swimming, not little league. I've worked with trainers and physical therapists from around the US and I've never once had one that said stretching is bad in a WORKOUT. Maxing out, I have no idea and don't care so much either.
