Wheel washing kills my lower back

I had a larger one for buckets, until I splurged and got bucket caddies..

 

Both my knees are in bad shape but using the kneeling pad ( mine is a 2" thick piece of very dense foam ) allows me to do my job fairly comfortably.

 

Whoever said work out I agree with them wholely. As well as stretch daily. This will help keep the flexibility especially if you work out.
Finally my back gets sore a lot less ever since I started busting out my abs exercises.

 

More specifically, make sure you are stretching your hamstrings and hip flexors! But never when your muscles are cold
