1.) Should the negative sets start at 75% of my 2RM on the first Monday, and increase in 5% increments over the 2-week period? It's what I've been doing thus far with the 15/10/5-rep sets.
2.) How many reps and sets should I aim for? 2 sets in the first week, 1 set in the second? Reps of 5?
3.) Should I do negatives for every exercise listed, or are there some that you would skip? For instance, I know compound lifts are important but is it useful to do negatives for both deadlift and squat, or is it sufficient to do just one of them?
