Floor press is alright, power lifters use it as more of an accessory than an actual main exercise. From a strength coach perspective the bench press is a more explosive/mass building lift compared to the floor press. Floor press could be considered the "box squat" for the bench and a really good tricep movement if you pause on the floor before you explode up since your triceps will be fully relaxed before the press.
I get a bunch of these
reactions when I do them in the squat rack though. Always brings the lolz.
