Chest growth!?

My chest didn't grow AT ALL until I upped my volume by a lot. I perform 3-5 sets (usually 4-5 unless I'm really tired)

Current chest routine and how I perform the exercise:

Barbell Bench Press: 3-5 reps, 2 second pause. Explosive as possible while maintaining form.

Chest dips to failure (if getting above 10 use weights to make it harder): Go down to just below parallel and back up, don't fully extend your arms until the last couple of reps and then really squeeze your chest on those, you should feel the bottom and middle of your chest burning.

Decline Dumbbells: Use a good weight that you don't need a spotter to help with. Really control this one, slower negatives and squeeze at the top, usually do about 6-10 reps.

Incline Flies: 8-12 reps, very slow negative keeping your chest contracted the whole way. Slowly lower it until your arms are just below parallel and come back up. Make sure to use a lower weight and keep your arms bent at about a 20 degree angle

Flies from a low cable: 8-12 reps, Keep your arms at about the same as above and really try squeeze at the top of the motion

Flies from a high cable: 8-12 reps, Same as above

I repeat the above on shoulder day but replace bench press with incline bench and do overhead press and seated shoulder press before doing this, so essentially I'm doing this routine twice a week.

As for mind muscle connection, the only thing I've found to work is posing. I usually practice this once every 1-2 days, sometimes multiple times a day. Really try and contract each muscle you are posing with. I've felt it's helped incredibly with my mind muscle connection to my chest and back which were my weak points last year.

You only work chest 1x per week and you're surprised that you're not getting results?

try high reps one, superset the next and strength the next, also throw in a taper week, one set of each exercise so as to give chest time to recover. have you tried plate raises??

I’d lift chest two to three times per week, but I’d do two things: 1) Cut down to two exercises (flat bench press and db flys).

On the bench press I’d go as heavy as I could for 4 sets of 8 reps (one workout a week with a 3,1,3, 1 tempo). Rest 2 - 3 minutes between sets so you can stay as heavy as possible. This builds muscle density that becomes more noticeable as you get stronger (and go heavier). The tempo lifts are going to hurt, and you’ll have to come down a little on the weight to be able to hold the slower up and slower down.

I’d do 4 sets of 8 on the flys, make sure you really stretch at the bottom and squeeze at the top (like you’re trying to crack a walnut between your pecs). The muscles are fatigued from the bench and now, you’re pulling in additional muscle fibers during that isometric squeeze.

Be sure to measure your chest before you start this program and then about 6 - 8 weeks later. Measure on the same day/time before a training session so you get a consistent comparison.
