80% TM When Doing 7th Week Protocol?


#1

Hi Jim,

Looking at running 5x531 from forever. 7th week protocol is coming.

The program asks for an 80% TM. If I’m able to hit 8 reps would that be roughly where I should be? If not, what should be my rep aim?

Question 2; if I can’t hit the reps do I just calculate a 1RM off what I hit then take 80% of that for my new TM?

Thanks!

80% is 7-8 solid reps, you can double check by using your current TM and the 1RM formula, which is: (weight x number of reps x 0,0333)+weight.
I.e. if your current TM on bench is 100kg, 85% (5 reps), your estimated 1RM is 116kg. 80% of it is 93kg.
If you use the formula putting the 80%TM (93kg) for 7 reps, it gives you an estimated 1RM of 114kg, for 8 reps it gives close to 118kg - both are give or take in line with the example estimated 1RM of 116kg.

You should have a good approximate idea of the number of reps you can get from your latest Anchor PR sets @95% of your current TM. It’s not bulletproof math but, give or take, 95% of an 85%TM equals to 80-81% of your 1RM. If you got at least 7-8 reps on that PR set, chances are that that’s your new TM since it’s in line with the 80% you need for 5x531.
If you got fewer reps (5-6) you probably better shoot for lowering the TM 1 cycle back in your TM test, which should get you 7-8 reps.
If you got less than 5 solid reps in your 95% week, it’s probably better to test the TM from scratch since you’ll probably have to take it back 2-3 cycles.
If you got more than 7-8 reps on your 1+ PR test, you could try increasing the TM as usual after the Anchor cycle, and test the increased one to see if you can get 7-8 reps. But I wouldn’t increase the TM more than the usual increase, even if you get a gazillion reps in the TM test.

  1. Just use the rep/max calculator - and err on the side of Way too Light. I don’t know the reps that equal 80% as this varies even more so than 3/5RM’s.

  2. Yes, see above.

If your reps are slow and you start too heavy, your results will be far from optimal. Build and train -don’t test and fail.
