What do you do to strengthen your lower back?

[jpaul]

Breast stroke and particularly
butterfly stroke should do something for lower back

yes .. both those strokes are guaranteed to stress/knack your lower back , versus crawl/backstroke, where, you have some twisting, but your spine is basically stretched/straight. ... have you had back problems

I don't bother with roll turns, partly for not jarring back, and, I just want to swim full lengths.

do backstroke, it best for posture

Breaststroke with the kicking/snapping part if not done correctly and pull your muscles, i dont do this one because it can hurt me (i have degenerative disc disease)

Wasn't suggesting any one with a back problem did it
Asked the op already if he had any back problems and he hasn't
Just a bit out of shape
And yes I have couple of prolapsed /herniated vertebrae and spinal arthritis and sciatica ~falling apart lol
I couldn't even manage crawl or backstroke
As you said they twist your back rather than bend it
I would sink with out a trace in agony before 1 lap of the pool lol
I would never suggest any form of exercise if I hadn't asked if someone had a medical condition that would be irresponsible of me
