Put your trust in these personal trainers. 

Haus No.3

Phra Khanong’s personal training studio comes from the Swedish trainer Henrik Olofsson who won Fittest Man in Thailand three years in a row from 2014-16. At his new Haus No. 3 fitness studio, you get tailor-made training programs in a gym that looks like an Ekkamai coffee shop, all white-washed walls, soft wood accents and dangling bulbs amid the green and shady Naiipa Complex. Sessions don’t come cheap. A consultation (B1,800) is required prior to the private training, which costs from B2,190-2,950 per  visit. Or you can get semi-private training for B1,390-1,950.

A gym that specializes in boot camps, personal training and small group sessions, Max Fit has just relocated from Sukhumvit Soi 26 to Soi 39.
