Would you guys say my 1rpm represent a weakness anywhere or seem pretty normal?
bench - 120kg 1rpm
squat - 150 kg 1rpm
deadlift - 140kg 1rpm
seated military press - 70kg 1rpm
Deadlift should be more than your squat. Unless you have any particular injuries? Might be a core/trunk weakness or incorrect form.
For example mine are:
Bench: 130KG
Squat: 170KG
Deadlift: 205KG
So quite evenly spaced.
