I'm looking for some 1-on-1 private lessons, I am a beginner.
You can, check out Fight 360, located at 22 Orchard Rd, in between MacDonald house and MDIS. You can check out the website at www.fight360.com.sg or email to [email protected] for further discussion.
Evolve MMA is well known in the region for having the best instructors and facilities in Singapore, so i'd recommend checking them out for sure. They do private training and they have 2 locations, one near dhoby ghaut mrt at PoMo Mall and another near raffles place at Far East Square. They have lots of beginners training in addition to the high-level training they do, so you know you'll be in good hands.
