Delta Fitness & ViperworX Muay Thai — quick take for visitors

Verdict: A well-rated local gym with an active Muay Thai program and helpful staff, earning a 4.5/5 from 86 reviewers. Open every day 7:00 AM–9:00 PM, the facility mixes solid equipment and Muay Thai coaching with a no-aircon, fan-cooled environment.

What guests consistently praise

Fully equipped gym floor with many treadmills and additional cardio machines, so waiting for machines is rarely an issue.
Muay Thai coaching presence and private sessions are available; one reviewer completed 10 private trainings with coach Jiap, including sparring, and described tangible technique improvements.
Location is convenient for local residents, within walking distance of nearby housing complexes and local shops.
An exercise guide posted on a pillar helps people who want workout ideas but are hesitant to ask staff.
A quirky, friendly gym cat at reception adds to the atmosphere and is mentioned as a memorable facility feature.

Where guest experiences contradict each other — what to expect

No air conditioning — multiple guests noted the absence of AC as a defining trait of the gym.
Fan coverage varies by account: one recent visitor said the many fans are normally enough, while another reported not enough fans during busy or hot periods. Expect variable cooling depending on time and season.

Pricing signals pulled from guest reports

Short-term access appears budget-friendly according to a 2025 review reporting a 100 THB rate compared with local daily rates of 400–500 THB at other gyms.
An older review from 2018 referenced a monthly membership around 1000 THB, indicating membership pricing may have changed over time; use these figures only as directional data and confirm current rates with the gym.

Practical training details visitors reported

Private coaching that includes technique work and light sparring is offered; one guest specifically recommended trying private sessions with coach Jiap.
Class and coaching availability align with the gym’s daily 7:00 AM–9:00 PM schedule, so both morning and evening training are possible.
The gym is described as almost never crowded, which benefits solo lifters and people seeking consistent ring or mitt time for Muay Thai practice.

Accessibility, payments and logistics

Wheelchair accessible entrance and parking are available, supporting access needs.
Contactless NFC payment is accepted, enabling card or mobile tap payments on-site.

Actionable visitor advice

Plan evening visits if you prefer cooler workouts; one reviewer specifically noted evenings feel fine despite no AC because of lower temperatures and fan use.
Bring a towel, water, and expect a warm environment during daytime peak heat—fan coverage is present but inconsistent across reports.
If you want technique-focused improvement, consider booking a block of private sessions with coach Jiap; a past client reported clear progress after ten sessions that included sparring.
Confirm current membership and drop-in prices before arrival — reviewer-reported rates vary by year and may have changed.

Bottom line — who should pick this gym

If you want straightforward equipment access, treadmill-heavy cardio, affordable local training, and accessible Muay Thai coaching in a neighborhood location, this gym checks those boxes. If strong air conditioning and guaranteed climate control are deal-breakers, look elsewhere. For people living nearby or seeking budget-friendly short-term access plus the option of private Muay Thai coaching, this is a practical choice.

Quick checklist before you go: check current rates, bring water and light clothing, ask about coach availability, and use NFC for the fastest payment experience.
