Thread: Few Questions about my Full Body routine

Here is my routine and below I will post my questions.

Workout A:
Barbell Squats: 3 x 5
Barbell Hip Thrust: 3 x 10
Barbell Bench Press 3 x 5
Pull ups: 3 x Failure (6/4/4 currently)
DB Farmer's Carry 3 x 50 Steps w/ 1/2 BW Each Hand
Face pulls 3 x 10

Workout B:
Barbell Deadlift: 3 x 5
Barbell Overhead Press: 3 x 5
Barbell Squats: Deload (135 lb as opposed to 185 normally) for 3 x 10
Barbell Row: 3 x 10
Db Overhead Farmer's Carry 3 x 50 steps w/ 1/4 BW Each hand
Face pulls 3 x 10

Rest days: Mobility and Abs/forearm/calves. I will do a 7 minute abs routine, use a forearm pully for 3 sets, and do 75 calf raises onto a board.

Note: on the hip thrust/row I am going for 10 reps because these movements are new and I want to ensure I'm getting my form right.
Note 2: This is a four day a week with a rest day in between each workout setup.

Question 1: Is this enough bicep stimulation? I feel some pump from the pull ups and barbell row but I am in question of whether it will be enough overall.

Question 2: Should I be doing anything besides mobility on rest days? I do not feel like it is obstructing my recovery but I feel like I am lacking knowledge of when my recovery is being obstructed.

Question 3: I am 5'9.. 172 lbs with 80 lbs of lean muscle mass. I have just recently went from a 3200 calorie diet to a 2800 calorie diet and have not noticed any strength loss. Is this a sign that I was eating too much or does it take a while for the new diet to effect strength?

Any thoughts/ideas/tips very much appreciated. Thank you
