I live in a townhouse and am separated from my neighbors by a cinderblock wall. In my garage it is pretty exposed.
I would like to hang a kayak, punching bag and pull up bar off of the wall.
Kayak will weight about 70 pounds (plus 10 pound for the hangers). Punching bag will weight 100 pounds (plus 15 pounds for the hanger). Pull up bar will weight 15 pounds plus it needs to be able to hold my 250 pound body that will be spasming out on it trying to perform a pull up (so I am guessing that might generate about 550 pounds of force).
Can I, and if so how would I go about hanging each of the three items listed above?
The heavy bag hanger will be this: https://www.amazon.ca/dp/B011UF54RW
Pull up bar will be similar.
I already hanged kayak and it seems to hold.
My biggest fear is cinderblock wall collapsing since I heard that cinderblock can't handle anything being drilled on it. It is supporting second floor and I don't want the wall collapsing.
EDIT: added pictures and more description

Based on your information I would have to go with toggle bolts. C-90 Hollow Block (1 1/2-inch wall) An anchor sized at 1/8 inches can take 310 pounds, at 3/16 inches it can take 700 pounds, and a 1/4-inch anchor in a 1 1/2-inch thick wall can take 1,390 pounds. This increases to a whopping 3,620 pounds for a 1/2-inch anchor with a 1 1/4-inch embedded depth. Good luck with those pull ups.
