This was the part of our viral GYM MATHS reel that caused the MOST controversy!
We suggested that you should generally be able to back squat more than you RDL… and you certainly had opinions!
So let’s explain the thinking behind it.
A back squat is a compound movement involving significant contributions from the quadriceps, glutes and hip adductors, with the hamstrings and core helping to stabilise the movement.
An RDL is a hip-dominant movement, primarily targeting the hamstrings and glutes, with relatively little movement at the knee.
Because the back squat involves substantial contributions from both the hip and knee extensors, there’s a theoretical argument for having greater load potential.
BUT here’s the important bit…
That doesn’t automatically mean everyone should be able to squat more than they RDL!
Limb proportions, biomechanics, squat depth, mobility, technique, training experience and injuries all influence how much weight someone can lift in each movement.
And importantly, there’s no universal scientific rule that your back squat MUST be heavier than your RDL.
Our original GYM MATHS reel was intended as a simple guide to encourage women to challenge themselves with appropriate weights and understand progressive overload, not a strict formula everyone should follow.
Now we’re curious…
WHICH CAN YOU LIFT HEAVIER?
BACK SQUAT or RDL?
