Reviews mention modern and newly added machines, plus free weights for training all muscle groups.
Several members describe the facility as clean, spacious and well-maintained.
Some members say trainers explain exercises clearly and provide patient, encouraging guidance.
One recent member found it uncrowded, with enough equipment to avoid feeling rushed.
Confirm access. Ask exactly what a day pass covers before visiting with friends, especially mirror-area access and time limits.
Clarify PT. Before joining, ask whether general training support is included and what personal-training charges or expectations apply.
Avoid heat. If treadmill work matters to you, check the cardio area's temperature first; one review found 1pm–4pm especially problematic.
Check support. New members should ask for an exercise walkthrough at reception rather than assuming ongoing guidance is included.

The Bottom Line
New Ultra Mass GYM is a large 24-hour facility in Naif, aimed mainly at people who want flexible access to machines, free weights and strength or cardio training. Reviews describe a 25,000-square-foot gym with newer equipment, plenty of space and, according to one recent member, little crowding. That makes it appealing if you prefer training at unusual hours or want more room than a compact neighbourhood gym provides.
The setup goes beyond standard lifting: reviews mention kick boxing, karate, yoga, Zumba, dance and billiards. Trainers are another strong point for some members, with comments about clear exercise explanations and supportive guidance, although that experience is not consistent. Several older and newer reviews say beginners were encouraged to take personal training and received less general assistance when they declined.
The main caution is customer service. Multiple visitors describe reception or counter staff as rude or unprofessional, while others report friendly and helpful staff, so the experience appears uneven. Air conditioning has also been a recurring concern, particularly around the treadmill and cardio area; one review specifically found it very hot from 1pm to 4pm.
Before joining, confirm what general training, day-pass access and any extra area fees include.
