If you’re going to exclusively for length right now I would add a few things to your routine. Before you start training get in 5 to 10 minutes of bundled stretches. There are a few different ways to do them. If you have the Lengthmaster you simply strap in twist your penis once or twice and then using the handlebars stretch outword. If you do not have a LM you can do them by hand by simply questioning your penis a couple times while flaccid and stretching out from there. The importance of this is the Tunica, being the single most limiting factor in making gains, is very tough and bundles release the Tunica to be more loose like to accept more expansion.
I think you should start doing three sets of expressive stretches within your routine. There are many different expressive stretches you can do. You can do the manually by gripping low on your shaft and stretching from there. If you have a bathmate or a Mityvac you can do hard-core stretches. If you have the Lengthmaster you can do either hole stretches or low grip chamber stretches.
Lastly, I would like to see you get into sessions per week of erect stretching. You can do this for 10 minutes to accomplish what you need to do. Basically erect stretches help to secure new length gains.
