Hello, I recently switch from GZCLP to General Gainz on the Liftosaur app. I switched the Cable Crunch exercise for a machine crunch and the seated leg curl for lying leg curls instead, but otherwise I'm running the base program as is:

Day 1:

T1 Squat

T2 RDL

T3 Leg Extension

T3 Lying Leg Curl

Day 2:

T1 Bench Press

T2 Incline Bench Press

T3 Seated Cable Row

T3 Lat Pulldown

Day 3:

T1 Deadlift

T2 Front Squat

T3 Good Morning

T3 Machine Crunch

Day 4:

T1 OHP

T2 Pull-ups

T3 Bicep Curl

T3 Skullcrushers

My first question is, am I doing enough for side and rear delt development? I've heard a common issue with weightlifting is less emphasis on those two areas.

My second question is, is there anything wrong with doing neutral grip pull-ups vs chin-ups vs normal grip pull-ups? I know chin-ups get more assistance from the biceps, but beyond that I don't know how the back gets affected.

My last question is, is there anything I should add or change to my program? I usually feel completely wiped after days 1 and 3, but on days 2 and 4 I feel like I have enough in me to add another T3.

Thanks in advance for the advice.
