Is is okay to get the back activated here?
How many seconds do I need to hold this? If I put it down right away, won't it count as exercise?
I don't know if I'm feeling any stimulation or not. I'm just doing 20 reps with 5kg within the range where my arms are shaking.
If you hold it and turn it like driving a half turn to both sides, it will break the front of your shoulder.
Is it normal for this to cause some stimulation on my back as well?
If you go down too much when descending, all the stimulation escapes. The key is to raise it again within the range of stimulation!
Why does it seem like breast stimulation works better?
If you do this while driving, it's really stimulating;;; They say you bite down hard when making a U-turn. If you have dental insurance, go for it.
