And do you start off with strength training and then move onto mass?
If it is your first week ever training..start off with endurance full body 3 non-consecutive days a week.
You can run through something like this as a circuit 2 sets of 15 each
Squat
Bench
Pulldown
Tri Press
Military
Bi Curl
Calf Press
Crunches
Then do 2 weeks of strength training..increase calories by 10%
week 1 go Mon wed friday 3 sets of 6-8 after warm ups
week 2 A-B split fashion, 4 sets of 6-8, Mon/Tu thur/Fi switching movements where possible and add shrugs and something for hams like stiff leg deadlifts
Squat
Deadlift
Bench
Row
Triceps
Shoulder
Biceps
Calf Press
Crunches
After that...
Instead of the 1x per week for the whole body..which IS good for the stength training range you outline...
If you want max muscle growth you would be better to do a 2 day split instead of a 7-day split.
Day 1 - A
Day 2 - B
Day 3 - Off
Day 4 - A
Day 5 - B
Day 6 - Off
Day 7 - Off
The rep range of 3-5 will develop mostly strength if you want that leave it as it is...if you want size and strength try 6-8...if you want mostly size go for 9-12.
Also, as you want to knock off some fat...that second day should be higher reps 12-15-25 to increase fat burning capacity in muscle...
After you warm up, start with the large muscle exercise - yes it is a great idea for growth!
Day 1 Squat first for example
Day 2 Deadlift first for example
Day 1
Squats (Four Sets of reps)
Stiff leg deadlift (Four Sets of reps)
Chest/(Four Sets of reps)
Triceps (Four Sets of reps)
Shoulders (Four Sets of reps)
Day 2
Deadlift (Four Sets of reps)
Back (Four Sets of reps)
Biceps (Four Sets of reps)
Calf (Four Sets of reps)
Abs (Four Sets of reps)
Finally..change the training every week!
See the variations links in the post I gave you....this shoudl give yo a sample anf the flavor of creating a progression...
