Talk to me about foam rollers

[NautilusLionfish]

I have all sorts of tight muscles and just restarted c25k almost a year after graduating my first c25k. I would like to buy an affordable foam roller for it band and all over but also strengthening my knee (sitting knee extensions). If you have used one, which ones would you recommend or advise me to stay away from?

I have a fairly basic one from Amazon - well two, one is quite "knobbly" and the other smooth. Both around £20 and do a good job. I honestly wouldn't be shelling out for Technogym kit for this particular item.

Thank you.

We have one from Asda it's amazing.
I would recommend watching a video on YouTube for the best way to use them, they are brutal but do work
