one more question I should have asked was age and how long you
been training. Also how many days a week you training? I'll guess
3.
As far as the training program is concerned - forget about training
muscle groups - train movement patterns.
What you are currently doing does "suck" so dump it quickly.
Day 1 (eg. Monday)
A1. Squats
A2. Bent Over Barbell Rows
B1. Static Lunge (Split Squats)
A2. Weighted Chins
Day 2 (eg. Wednesday)
A1. Deadlifts
A2. Bench Press
B1. Romanian Deadlifts
B2. Military Press
Day 3 (eg. Friday) - Repeat Day 1
Alternate between A1 & A2, B1 & B2
Workouts 1,2,5,6,9,10
Sets: 3-4
Reps: 5
Tempo: 3-0-1-0
Rest: 60-90 sec
Workouts 3,4,7,8,11,12
Sets: 2-3
Reps: 10
Tempo: 2-0-1-0
Rest: 30-60 sec
Just a basic program - without a full assessment I am just guessing
but this is better than what you were doing.
