I am trying to anchor a woody climbing wall to a cinder block garage wall and have settled on anchoring boards into the cinder blocks then building from there. so anything anchored there would be sharing a load of me-200 lbs, the plywood base and frame - 50lbs. plus any force generated by my jumping around on it.
Secure the wall to the floor of the garage with something like Simpson Concrete bolts - they work like Tap-Cons, but are larger and have a greater shear strength. To avoid having the garage wall, roof, and the climbing wall collapse on top of you (that's not even good avalanche practice), anchor the top to the top plate of the garage wall. It should be anchored into a bond-beam at the top of the wall with 1/2 diameter bolts. You could also hang the wall out a little further, and secure the top to several ceiling joists or roof rafters with framing anchors. Just do not attach the climbing surface directly to the block wall; either you will pull the anchors out, or push the wall over. Look at the Simpson-Strong Tie website for bolts and framing anchors. [You must have a pretty tall garage.]

The blocks themselves are designed to carry a deadload from top to bottom. The walls of your blocks are to thin to carry any outward pressure, like you bouncing on it. I wouldn't trust cinder blocks to hold wall anchors. If you try to hammer-drill the middle of a cinder block, it will shatter. Anchor your boards vertically to the wall so that the floor is carrying any downward force. It would be best to install a deadman board to the ceiling joists which would hold your vertical boards tight to the wall. Anchors in the mortar joints would assist to carry the load more than anything else. Big fat toggle bolts would suffice in the application I described here. Edit, Use expansion bolts, or PL400 construction adhesive with concrete nails to secure wood to the floor. It also occours to me, you could just frame up a stud wall in front of the block wall. Anchor it to the floor with glue and nails, or expansion bolts, and nail it to the ceiling joists up top.
