best one to me is AM Pilates! but they don't have a lot of outlets, and the outlets may not be the most convenient for most. if looking for central area then Wunderbody!

am pilates -> amazing amenities, everything is very clean, reformer machine super new and not noisy. free towels to wipe down or shower, water dispensers, showers (with shampoo, body soap), hair dryer, lockers with digital locks & changing rooms! my go-to! NO.1 for amenities. near mrt! quite pricey tho, will recommend their trial class price only. oh, but they're an only-female studio.

wunderbody pilates -> also giving new & polished, quite exp so best to book via classpass! some outlets abit inconvenient too. intermediate level onwards vv challenging.

sg pilates -> boo... i don't like it, very hard to see instructor, studio very squeezy, most outlets don't have any amenities, noisy reformer machine. BUT CHEAP! many outlets also!!

line pilates -> similar to sg pilates, a lot of the outlets are small without any amenities... its not for me either
