What happens when the person lifting the weight in both cases (heavy weight and light weight) is aiming to lift until failure?

Imagine this. You're in college, and you have a test tomorrow in 3 different subjects. Someone else has a test tomorrow in only 1 subject. Which of you can study better for the exams you'll have the next day? Obviously, the person with only 1 subject to study for.

When your muscles are given multiple stimuli, the same thing happens. You adapt better to 1 rep range. This is called "the law of least effort".

We tend to adapt better to fewer stimuli rather than to more stimuli. Its also the reason I suggest you work with only 1 or 2 exercises if you have 6 sets, rather than breaking all those sets down across 4 different exercises. You dont "hit the muscle from different angles". This is impossible due to the all-or-nothing reaction.

If you were to do low reps and high reps in one workout, you would get better at both things, but you'd not adapt best at either. Its better to let one workout be the high reps workout, and another workout be the low reps workout. There's some situations where this doesn't apply though - namely if you have specific goals or are trying to create a specific metabolic environment (C days on the ABC program, for example).

Also, if you do intend to train for speed in the same workout that you'll be doing normal weight training, always do speed / plyometric work first. This is because they are dependent on nervous system involvement, which wont affect regular weight training as much as weight training will affect nervous system involvement.
