Yesterday I tested my maximum on the Curl (back against a wall) :
Left Arm : 24,
28.5, 29 under // +1.5kg in 28 days
Right Arm : 22,
26.5, 27 at // +1.5 in 28 days
Both the 1x1x95% and the 6x1x95% Arm made the same gains. Like I thought it really seems volume has no influence on stimulation.
Floor Press Right Arm : 36, 39.5
Deadlift : 155, 173.75
