I am doing a 3 day a week FBW. I am basically trying to reach near failure with each exercise. Recently, I was forced to increase my load on my bench press because I wasn't reaching failure anymore.

The problem is now that my arms are giving out prior to my chest reaching failure. And since I am only doing 1 compound exercise per major muscle group, I am afraid that my chest is going to get neglected.

Sample wk-out M-W-F
Chest - Flat bench press
shoulders - overhead press
back - lat pulldown
lower back/hips - deadlifts
Legs - Squats
Calves - Calf raises
Arms - Bicep curls or Skull crushers

I do vary the workouts with reps and sets, different exercises, and some days dumbbell only.

Is there a technique I can use to keep this from happening? Or should I consider lightening the load and adding an isolated move like pec dec flys or cable crossovers?

What do you mean by this?

I think he means that his arms tire before his chest. this is pretty normal, just keep pressing and your arms will get stronger. and besides, bench press isn't really the pec exercise everyone thinks it is, there's a lot of triceps involved!

Start training more arms, Or train arms harder. I know it sounds simple, but that is usually how things go.

I meant that my arms get really weak. sorry for the confusion.

Is there a better compound exercise for the chest than bench pressing?
Or could just use more isolated moves instead of bench press?

why are you training to faliure every session,there is no need,either for strength or hypertrophy,all you are doing is setting yourself up for cns burnout.

Bench press works your chest and triceps (as well as shoulders) Right now your arms are the weak link. Continue doing them and things should level out

Bench press is a good exercise.. mix it up, use DBs, BBs incline, decline, etc. And like Goergen says, train your arms more (specially the triceps) to fix the weakness.

ok. thanks alot for the advice
