Which joist attachment method is better for adding a pullup bar in the basement: spreading the weight across the subfloor or bolting directly into the joist itself?

I’m thinking about installing a pull-up bar in the basement. Just wondering, from a structural point of view, do you think it’s better to attach it to the joists with a bracket or bolt it directly? I know joists can support a lot of weight, but I want to make sure I’m not overloading them. Do you think either option would be safe, or do you have any recommendations?
Either one would likely work. Personally, I have more confidence in the second one. With the top option, you could opt for 2×6 and attach it using simpson strong tie screws to the side of the joist. For the bottom option, you could use strong tie screws to attach that horizontal board to the bottom of the joists
Option one might be more sturdy just because of how the weight is distributed
Can you please make sure to turn off the lights before leaving the room?
I personally chose option one for myself, and I weigh over 250lbs.
2×6 and a one inch rod
I prefer option 1. Take the 2×6 all the way up to the sub-floor, then use four 2 1/2″ x 3/8 lags with washers. This approach should provide sufficient support. The load should not be a cause for concern. I would recommend avoiding placing it next to heavily drilled floor joists, as shown in the photo. However, even in that scenario, the load should still be manageable.
I prefer option 1. Personally, I feel like it might wobble and become loose and swing. However, if you choose option 2, my recommendation would be to use bolts that go through the board, along with washers and nuts on the top side. Instead of solely relying on screws, this method would provide more stability. For extra strength, you could add a second round bracket on the top side, run bolts to sandwich the board, and secure them with lock washers and nuts. This setup would be extremely strong. Just ensure that the board itself is securely in place, as the screws used would then be the weakest link.
I personally prefer the first one. You could also think about including diagonal supports on both sides. This will prevent the whole setup from wobbling in case there’s any horizontal force, like when doing CrossFit-style pull ups 😜.
The first one is sturdier and has a classier look since it depends on the strength of the fasteners.
I love the above-the-door option from Dicks. Just lean into the door frame and secure it with 4 finish nails, haha!
The best option is Solution 1
#1 is the winner. The screws are situated next to the downward force. In #2, only the screws are keeping the pipe in place on the beam, so only the screw threads are supporting the weight. In both scenarios, all the weight is transferred to the joists (which provide ample support in either case), but only in #1 is the weight supported by more than just the threads of the screws.
