I want to make a homemade pullup stands to do my exercises in. My plan is to get to buckets, put two 7 foot ply woods on each bucket, drain the concrete mix, and finally, insert a bar on top. My question is, how many pounds of concrete mix will i need?, will it hold me?, and how do i go about mixing the concrete with water, pouring it?, and how long will it take to dry? note: the wood is 8inches thick. The buckets are large and wide, about 1 1/2 feet long and about the same in width.I am 6'3 240 pounds

concrete expands when it dries. Your wooden posts might end up getting crushed.
Also, your buckets will probably crack open.
Also, they don't sound like they're close to being big enough.
The whole contraption is going to be quite unstable without some form of bracing. Even if you had large enough concrete anchors, having about 6 feet of post sticking up is going to be a lot of leverage - even if they're 8 inches wide (since I assume these are 2x8 studs, not actual plywood sheets? and in order to stick a post through, they would have to be arranged so that the large side of each post was perpindicular to the pull up bar...which means that you'd have 2 6 foot lengths of 1.5 inch thick wood rocking back and forth under the weight of a 240lb man, the weight of the bar, and the stress on the poorly braced joints.
...actually, 7 feet is probably way too low for you if you're 6'3" anyway. I'm only 6'1" and a bar 8 feet in the air is nearly too short to do comfortable pull ups. Plus, you probably won't just rest the bar on top of the posts, othewise it would roll off.
I suggest you rethink your design.

two parts sand to one part concrete and 2/3 part water by volume measure. Two hundred pounds of sand to one hundred pounds of concrete. You may need two inch by four feet of ree-bar for your body weight.

As an expert my answer will be : ' Don't Try this . '
Wish you a happy exercising without your buckets and sticks .
