<human>: Can you summarize the given text in a few sentences?

Today, I went to the gym, did my leg day workout, then abs, then started running. By the time I hit half a mile I was already pretty tired so I wanted to get the workout done quickly, I turned the speed up a bit in order to get it over with (some regrets). While coming up on the halfway point, I got a snapchat from my friend, and was about to reply with a video of me flipping him off while running. As I was about to send it to him, I accidentally clicked the wrong username in my friends list. This girl I have been hitting on recently was the only one selected to be sent to, as I was about to change it back to my friend, I missed my stepping on the treadmill by stepping on the side part of it rather than the conveyor belt. I slammed forward, got the wind knocked out of myself, then proceeded to fall backward onto the belt again, sending me into a somersault flying off the treadmill. While in the process of falling I accidentally sent the video of me giving the camera the middle finger to the girl I like, then throwing my phone backwards into the gym wall. My phone didn't turn on again until I plugged it in and realized I sent the video to her. After falling, I stood up got my keys off the key rack and got in my car and left. My headphones are still plugged into the treadmill and my gym bag is in the locker room. Don't believe me? There are plenty of witnesses trust me.
<bot>: Running on treadmill, take snapchat of middle finger, fall off treadmill, accidentally send it to crush, walk out of gym leave headphones plugged in and gym bag in locker room.
