Yes, it’s good to have a spotter... and to use safe equipment and use it properly.
But don’t dis using heavier weight. If you stuck with the pink dumbbells, you’d get no where.
Exhibit 1:
Yes - spotter is good.
For my home gym I have a safety cable set-up hung from the floor joist’s when doing presses.
My friend leaves the collar locks off and if he gets in trouble just tilts the bar and drop the plates on one side, then the bar tilts to the other side and drops those plates.
I’ve never tried that...
I just retired as a NASM fitness trainer after sixteen years. I am a female and I would only train men to a certain point because I could not spot them as they progressed. A spotter at ANY gym should be an absolute must.
