Where to get Epsom Salt ?

I did foam roller,stretch then had a shower to clean up (2-3 mins?) and let that water run in the bath then topped it off with cold only to just above thigh level and sat in it for 20 minutes. While I haven’t been out long and the next few days will really tell it feels good and refreshing. Possibly didn’t have enough ES so next time will put in 500g.

Sady, feels like mauled by a bull? :eek:
