Week 1 – sets of 5 reps starting at 50% of max. 5kg jumps between sets.
Week 2 – sets of 3 reps. 5 or 10kg jumps between sets. Stick w/ 5kg jumps if you start w/ 5kg. Stick w/ 10 if you start w/ 10.
Week 3 – sets of 2 reps. 10kg jumps between sets.
When you come to a weight that you know you won’t get for the required reps, stop there. Repeat this cycle over and over again.
Example: Squat 70×5 75×5 80×5 85×5 90×5 95×5 100×5 105×5 – 110×5 too heavy to get for 5 reps? Stop at 105×5. When you get to your 3 rep day, you’ll more than likely be able to handle 110×3 and probably more; so at least you’ll be handling more weight.
Very simple. Very effective. Easy to remember. Just go lift. Good luck.
