Tried this below routine for 6 weeks and it was very difficult but my lifts before were:

198 weight
300 Bench
405 Dead
455 Squat

After 194 weight
315 Bench (easy)
435 Dead
485 Squat

I also don't recommend this for "hard gainers". You will be so wiped out after the first week, second week you get in better shape, then each week you can really see the results. Obviously these are all work sets, warm-up as you usually would.

Day 1
Bench 10 x 5 with 160 lbs of chains
Pull-ups 10 x 5 (Tough for me at first, by the end I was using a 15 lb db)
Bradford Press 3 x 10-12
Kettlebell between the leg swings 2 x 20 (switch hands every other rep)
DEEP Squat 1 x 6, 1 x 20
Incline weighted sit-ups 1 x 20
Toe Raises 3 x 25

Day 2 LOW impact cardio 45min (I swim)

Day 3
Close-grip Bench 10 x 5
Machine Row (chest supported) 10 x 5
Upright Rows 3 x 10-12
Kettlebell between the legs swings 2 x 20
Deadlift off of a 45lb plate 1 x 6, 1 x 20
Leg Raises 1 x 20
Toe Raises 3 x 25

Day 4 Low impact cardio

Day 5
Bench with feet up 10 x 5
Pull-ups 10 x 5
Lateral Raises/Front Raise/Shrug superset 3 x 10-12

Toe Raises 3 x 25

Day 6 Off

Day 7 Low impact cardio

Day 8
Repeat Day 1... etc

I was in a rut on everything, blasted out of it!!!!! I went back to a more traditional workout now and all my old "stand by's" have increased as well. Let me know how it works for you and replace any excersise with one you feel more comfortable with. The important thing is don't do what you have been doing...
