Assuming the goal is to progress in size and strength using weight training, what are you thoughts on a routine that either:
1) Uses a rep range of 5-8 (for example), where you start workout day 1 with a weight heavy enough that you can do 5 reps but not 6. And over the next few days/workouts, you use the same weight but aim for a 6th rep (assuming correct form and same speed), and over the next few workouts, a 7th, and finally an 8th rep (means you became stronger overtime). THEN you add enough weight to the same exercise so your next workout will end at 5 reps again, and you challenge yourself to reach the 8th rep over the next few workouts.
2) A routine that uses a fixed rep limit, say 5 reps dead, so the weight is heavy enough to complete 5 reps but not a 6th. In the next workout, you add a little weight (2 lbs for example), and aim to do 5 reps again.
My thoughts on number 1 is it becomes a nice challenge but I'm not sure if it will help with the goal of strength and size. My thought on number 2 is it will be quicker to stall because adding weight to the bar every workout will mean I will struggle with that weight if my strength doesn't keep up, and I may not have weights small enough to add in very small increments.
Please can I have some thoughts on this? I like the sound of method 1, but is there anything wrong with it?
