Every good set extender has it's place. I particularly like forced reps, but I may do too many of them sometimes. Although if you do forced reps of every set, just watch out for overtraining. I prefer to save my forced reps for an all-out last set. In my opinion, forced reps with a heavy weight may be enough to get your body used to that weight, and make it stronger. But rest pause just increases time under tension, which I don't see as a big strength booster, but might be better utilized in bodybuilding.
i think forced reps are great but i got more out of finishing of with a few extra negatives also i think rest/pause is a verry good tool for the bench squats and deads worked well for me anyway put like 30 pounds on my bench in 4 weeks
Use rest pauses sometimes, forced reps others however if your pushing yourself i see no need for more than 1 or 2 forced reps, I know when spoting someone i HATE having to lift the whole weight when they are trying 3-5 forced reps!
