I use the 5/3/1 every 3 weeks and find it great for improving explosive power and upping my lifts. Make sure you are lifting between 95-100% of your 1RM to ensure max gains. Also when doing this I aslo superset each exercise with a contrast plyo set ie. Squats ss CMJ’s, Bench Press ss Powerbag Throws etc.
Remember to ensure you get the correct rest between sets to insure you’re able to give max effort so you are recruiting your fast twitch fibres.
