> 1 set of 3-rep max of each of the major lifts

Could you elaborate your training regime?

If you can do 3 reps of bench with 100kg-s, you do:

1. bar x 10, 2. 40 x 10 3. 60 x 5 4. 80 x 5 5. Then do 100 x 3

And then you move to squats and deadlifts with the same approach.

Is this more or less what you did?

No just 3 reps of each then out

So you just start with your 3 rep max with no warmup at all?

I'm not sure if I would start deadlifting with my 3 max without proper warmup. Or any heavy lift for that matter.

What was your 3 rep max for the big lifts?

The nice thing about a deadlift is that, if you're unexpectedly weak that day, the weight is below you.

No warm up but I was 35 yo
