Weightlifting

So currently in football we are weightlifting and conditioning for the upcoming year. For the past week of weightlifting we have been maxing out, basically means you do as much weight as you possibly can but only for one rep. I haven't been to pleased with most of my Max outs because i feel like i should be doing more. On the other hand, today we dead lifted witch is squatting down and lifting the bar up to you knees while standing straight up, and keeping your back straight the whole time. I managed to max out at 300 pounds for dead lifting which i feel is a great accomplishment for me.
