To the people who can perform a 100 push ups or are in the military, should I lock out my arms at the top?

Whenever I've seen someone claim to be able to do 100 push ups and later observed them doing push ups- they're nowhere near going through the full range of motion, they're pretty much just pumping a short distance up and down, so I say fuck it man stop short of locking out your arms.

No you shouldn't. It's just like sit ups. You don't come all the way up. Almost tho. Keep tention in abs and feel the burn.
Knox what I mean. Not sure if I explained it correct.
I used to do 10 reps of 20 sit ups ( crunches ) and got the most out of them when I could feel the burn holding just b4 the top end

I'm curious, too. In fact, you should add a "see results" option, because there will be far more people who are curious about this than there are people who can do 100 pushups.

If your arms are holding a lot of weight/force, YOU NEVER LOCK YOUR ARMS

thats the same as doing a bench press, whenever im high rep stuff like 20 plus reps I try not to lockout everyrep because it tears up the elbows over time
