Adding the weight of the dumbbell bar it turns out to actually be 41 kg (90 lb).
Today I just did this TGU to grease the groove (GTG).
Did it first try on my strong side (right) after two warm up TGUs with 21 kg.
Took me three tries on my weak side (left) after same warm up.
Form and flow not perfect… yet. 🙂
But thats why we do GTG exercises.
