I like them for strength when I do such kind of things. I like to go heavy with singles and ample of rest in an A+A method fashion, namely to repeat. This is good for getting decent volume with decent technique in. Half a year ago I did when I remember correctly sessions leading to an hour.Probably more effective for conditioning than for strength.
Yes.Are they effective for strength and conditioning?
I did today a longer double thruster session for singles for an hour. My hands did not want to snatch a lot.
I experimented early spring for a few weeks with this kind of double work. I think they are great for going heavy for singles and doing repeats with them.
They get better with each rep as the nervous system amps up and decent form can be maintained til the end.
