@786man Yup for one leg session, I only do 5 sets.
I only do one exercise in my leg training session.
My training split is push legs pull. Train 6 days a week.
Day 2 it's barbell squats. Day 6 is Romanian deadlift.
I carefully track all sets and reps in my log book so I can track progression.
After 3 months, my numbers will start to plateau. At this point, I replace the exercise with another.
But in short, fewer exercises but higher training frequency.
It takes 10 to 20 sets per muscle per week to stimulate hypertrophy. Anything more could be junk volume.
Fewer exercises lead to better mind muscle connection for that exercise.
To learn about periodization, exercise selection and more, I recommend looking up Renaissance Periodization, Alexander Bromley or Geoffrey Verity Schofield.
