I went from 14 to 16 reps the week before my pro-combine in january by doing this workout:
Set 1: Flat bench: 225, Max reps to failure, last rep should be lifted by your spotter... basically a negative 1:15 rest
Set 2: Flat bench: 225, Max reps to failure, last rep should be lifted by your spotter... basically a negative 1:15 rest
Set 3: Flat bench: 225, Max reps to failure, last rep should be lifted by your spotter... basically a negative 1:15 rest
Set 4: Flat bench: 225, Max reps to failure, last rep should be lifted by your spotter... basically a negative 1:15 rest
Set 5: Flat bench: 225, Max reps to failure, last rep should be lifted by your spotter... basically a negative 1:15 rest
Set 6: Flat bench: 225, Max reps to failure, last rep should be lifted by your spotter... basically a negative 1:15 rest
What did you expect, Some elaborate program? I did this every day that I was physically able to for 10 days before combine, with 2 days rest before the morning of pro-bench. Your arms are going to want to fall off after each workout... Immediately after the bench session, take some high quality protein, and a large amount of water... 60 minutes after, do chyrotherapy for the triceps (I just used very cold running water) and immediately following that take a 1hr 30 minute nap to induce growth hormone production. (Roughly 1 sleep cycle) I also did 4 self-hypnosis sessions the week before combine, in order to gain confidence in ability, and in order to lose mental block... I've been invited to training camp, so i did something correct.
I am vevy fast twitch dominant so 2 reps is huge in my eyes. You may do better, or worse. Maybe this will help. Peace.
