I've been 'stuck' at 240 lbs in my bench press. My biggest issue seems to be in the lift off from the chest. From what I've been reading, this could be due to the lack of speed/initial explosive power. What exercises would you recommend to improve this part of the lift.
Certainly you're at the point where you have to focus on technique, and doing so will not only help you push past plateaus but also avoid injury.
The following technique list is taken from Power to the People Professional, and all adds up to an explosive push. Notice the focus on deriving power through your feet and directing that through your body! The bench press is just as much a full-body exercise as the deadlift or squat.
