This one’s a random question

but I am curious— I have seen the videos and pictures of WP Beast and the back packs look humongous! How would you recommend to prepare for that and the pushups? Thanks for making this thread!
That's a great question and the advice given above is awesome! I didn't prepare for the rucks or really for the pushups because nobody told me how intense they would be so I'm glad you're asking.
For the rucks, if you already have boots wear them when you ruck, but if not then tennis shoes are perfectly all right. You may not own an actual ruck but even putting some weights/bricks/heavy things into a back pack and walking on a treadmill at an incline will prepare you more than doing nothing. Maybe do a hill interval workout, and if you're like me and live in a place with no hills, the treadmill will be very helpful. For example start with no weight and walk at an incline of 3 for .2 miles, then increase to 5 for .2 more and go all the way up to an incline of 10 and then come back down every .2 miles. You can make this workout more challenging by starting at higher inclines or walking for longer distances or carrying more weight, but please start slow and build up because you don't want any injuries. Make sure you have water too because even though you're just walking, it takes a lot out of you!
For pushups, work on tricep pushups. If you can't do tricep pushups, find a workout buddy who can help you. Do the negative (so start at the extended position and go down slowly) and have your buddy pull your hips up to the starting position. Once you feel like you can do even two on your own, build up over time. For the APFT (Army Physical Fitness Test) the minimum is 18 pushups I think, but the max is 42 in two minutes. When I first took the APFT on the second day of Beast, I could only do 19 pushups, but my roommate helped me every night to practice pushups and at the end I did 28. A year later, I maxed my first APFT pushups, so it is possible - it just takes time and doing pushups is the only way to improve pushups, unfortunately.
For pull-ups, as a girl if you can do even 1 full pull-up, that is considered above average. I recommend getting a pull-up bar that you can install above your bedroom door, and every time you enter you bedroom do as many pull-ups as you can. Keep in mind that a pull-up according to West Point is a pronated grip (palms away from your body) and a full extension at the bottom (so no bend in your elbow). If you can't do one pull-up yet, that's ok! Grab a chair and do the negatives or have your workout buddy spot your knee/thigh and help you get up so that you can do the negative and slowly come down. I couldn't do one pull-up before I started prepping for the CFA, tested 3 on the CFA, and can now do 6, but once you can do one, it's amazing how quickly you can add reps. Hope this helps!
