Is it recommended to go 7 days a week?
Yes. 6-7 days per week is the norm with hanging
When first hanging do you let it hang?
I'm not sure what you're asking here? Are you asking how much weight to start out with? (if so, start out light with just a couple of pounds)
when he says squeeze the blood out of your glans before hanging, how do i do that?
Just lightly squeeze the glans (head of the penis) between your thumb and pointer finger. This will collapse the glans a little, giving the glans a little room to expand when weight is applied without building up too much pressure.
what the hell are split sets?
That is where you split your sets up throughout the day. Instead of (for example) 4 sets at 20 minutes each done back-to-back, you do a set in the morning, a set at lunch, a set at dinner time and a set before bed (for example)
he states that using a ADS after is a bad thing, but I've read everywhere that and ADS is perfect to avoid turtling and to heal in a elonged state
Everyone has their opinion. Personally, I think ADS/extending after hanging can be beneficial
And since i've never hanged before, the beginner routine he list is probably most optimal am i right?
Yes
Good luck
