Viking Ocean has a Nordic Bath technique with hot and cold, hard to describe, but works wonders for aches and pains and general arthritis. (Small heated pool, Ice room similar to cryotherapy use, and a water pail suspended from ceiling.) Super after long trekking and walk. There is a sufficient gym near the area of the Spa facility with excellent weights, bench, work out equipment, bands a few ellipticals and stationary bikes. Always a few regulars in the gym that we see, rare to see any formal classes. (retired PT)
