Do I need more calories?

Not sure if this would be more appropriate for the Training forum or here, but here it goes:

34yo, 5’11" ~220lb, 24% body fat (according to Globo Gym electronic measurement) Sq: 4001@8.5
Press: 170
1@8.5
Bench: 237.51@8.5
DL: 365
1@8

I realize that the stronger I get the slower my progress will become, but I don’t think I’m strong enough yet that +3 pounds to my squat e1RM (423 at end of 1st round of Bridge 1.0 vs 426 at end of 2nd round) over 8 weeks is reasonable. I also think that for someone who has been lifting for 2.5 years, I should be stronger across the board than I am.

I’ve tended to assume that since my weight has been steady between 220 and 225 over the past year+ of lifting (ie, I’m not losing weight), that my caloric intake is sufficient. But I’m also not getting as much protein as I probably should. Last time I tracked my macros on myfitnesspal, they looked like this: Cal: 2600-3000
Carbs: 180-190
Fat: 145-185
Protein: 130-140

Do I just need to be getting more protein? Am I overshooting RPE? Both?

I’m currently on my 3rd run through of the Bridge 1.0 (after having been on Texas Method). I made what I think is good progress on upper body lifts during the first 8 week cycle, but now am noticing a pattern that in weeks 2-4 I am having to back off after the first or second set @8 for press and to a lesser extent bench (though still making slow progress from 8 week cycle to 8 week cycle), and my squat calculated e1RM isn’t moving up much at all. Deadlift is still progressing, but I think that’s because it had historically been my weakest (proportionately) lift due to some form deficiencies.

As an example, here are my presses from weeks 2-3 of last run through vs current.
Iteration 2 Week 1: 1505@8
Week 2: 152.5
5@8, 152.55@9, 147.55@9, 1405@8
Week 3: 147.5
5@8, 147.54@9.5, 1355@8.5, 135*5@8.5

Iteration 3 Week 1: 147.55@8
Week 2: 147.5
5@8, 147.55@8, 147.55@8, 147.55@8.5
Week 3: 150
8@8.5, 1458@8.5, 1458@8.5, 145*8@10

Thanks for any feedback!

It’s unlikely to be your calories. It may be your technique, your motivation to train, overshooting the suggested load, or perhaps you require some different training after getting ~16+ productive weeks out of The Bridge
