I am contemplating 2 modified 5x5 routines to run for 12 weeks. One is a 4x per week routine, the other a 3x per week routine. I am 57, been training a long time, and not on any gear. I'll be eating about 600 kls above baseline. There are many exercises I cannot do... BB squats, dead lifts from floor, chins, BB bench, DB inclines and flat, fly's, overhead press, due to chronic physical problems. Yes, I'm limited but I still make progress. On the 4x5's, each set will be with the same weight after warmup. Once I complete all 5 reps, I'll bump up weight slightly for next time.

Which one looks best:
Mon:
Decline Smith Press: 4x5
Low Cable Crossover: 2x8-10
Peck Deck: 2x8-10
DB Lateral Raise: 2x8-10

Tue:
Rack Pulls: 4x5
Row: 2x8-10
Straight arm cable pullovers: 2x8-10

Thu:
CG Bench: 4x5
BB Curl: 4x5
Weighted Dips: 2x8-10
Incline DB Curls: 2x8-10

Fri:
Leg Press: 4x6
DB Squat: 2x8-10
Leg Curls: 2x8-10
Calf Raise: 4x8-10

Or my 3 day plan:

Mon:
Decline Smith Press: 4x5
Low Cable Crossover: 2x8-10
Peck Deck: 2x8-10
DB Laterals: 3x8-10
Weighted Dips: 4x5

Wed:
Leg Press: 4x6
DB Squat: 2x8-10
Leg Curls: 2x8-10
Calf Raise: 4x810

Fri:
Rack Pulls: 4x5
Rows: 2x8-10
Straight arm Cable Pullovers: 2x8-10
BB Curl 4x5
Incline DB Curls: 2x8-10

I'm leaning towards the 3 day per week routine.
