Usually, I do skull crusher exercise (1st or 2nd exercise of Triceps day and neutral position with an EZ bar) 3 sets with following weights (8-11 reps range).
Earlier I used to do 20kg max (for 3rd set). Increasing weight in time.
1 : 15kg (7.5kg each side) 2 : 20kg (10kg each side) 3 : 25kg (12.5kg each side)
While doing 3rd set, around 7th or 8th rep, I feel sudden loss of strength in my arms and I feel like dropping weight on my forehead or nose.
It only happens with skull crusher and that too with 3rd set (that too at 7/8th rep!), not with any other exercises.
Its happening from last 3-4 weeks.
What could be the problem?
