Could you please share some insight on the following.
I recently (1-2 months ago) started doing loaded dips with extra weight. Before that I normally didn’t do any dips.
I do them either with a dumbell between my legs or I use a dip weight belt. I use between 100 and 200 lbs additional weight for 3-10 reps, multiple sets, however most of the time the first reps especially the first one are very hard and the 3/4/5/6/7 rep start to get more easier. Even with a weight I can do more than 10 sometimes the first rep feels very unstable and crushing.
Is the reason for that my nervous system or do the next reps get easier because of stored energy and stretch reflex?
