Split vs Full Body

49DegreesNorth

Hello to all
started lifting 5 years ago.
Used with success Lyle McDonalds UD2 and Stubborn Fat solution

I am 50 years old, 5'9" tall, weigh 182 lbs and am at 9% BF.
I have pretty much reached my goals also thanks to Lyle's books.

After UD2 and SFS, my Workout program has been for the past year:
- 3 days Strength (Legs, Push, Pull)
- 3 days Hypertrophy (Legs, Push, Pull)
- 1 day rest

Week 1
5x5 for strength
4x12 for hypertrophy

Week 2 - same weight
5x7 for strength
4x15 for hypertrophy

Week 3 - weight increase
5x5 for strength
4x12 for hypertrophy

Week 4 - same weight
5x7 for strength
4x15 for hypertrophy

Etc

I work out of a home gym, with a Cable machine, squat rack, elliptical, treadmill and free weights (Dumbbells and Barbells, plates)

I am starting though to feel the "weight" of the years (pun intended ;D )
Feel I have to cut on the volume to prevent injuries and overtraining.

So I have recently started a full body routine, Mon-Wed-Fri, and reduced my weights to 80% what I would normally be able to lift

Monday 3x10, maintaining weights constant Wednesday 3x12, Friday 3x15 and then increasing weigh on the following Monday, etc
Between sets 1' Elliptical at 60% to keep heart rate up

Mondays

Flat Bench Press

Seated Overhead Barbell Shoulder Press
Bench Dips
Inclined Flyes

Forearm Twists
Cable Rows
Concentration Curl
Single Leg Calf Raise

Wednesdays

Weighted Pull - Up
Narrow grip Weighted Pull - Up
Incline Close Grip DB press
Pronated Dumbbell Bench Row

and applying Lyle McDonald's Stubborn Fat Solution's HIIT on Tue and Thu (5' warmup, 15" at 90%+45" rest x 10, 40' at about 130BPM followed by 30" at 80%+30" rest x 10)

I am eating at my maintenance (including exercise) about 2,700-3,000 cals, 35%P35%C30%F (about 1.4gr/lb of Protein)

I would like to keep at around 9-10% BF, and this winter will increase my caloric intake by about 500cals for a lean bulk.

But I'm thinking that probably my volume is too high. For now it's working but I'm afraid soon it will hinder my progresses
Any critique to this is greatly appreciated
I love to hear from who has more experience and can help me tweak and improve effectiveness of my training and nutrition

Thank you to all
