CrossFit Tay Ho in Hanoi, Vietnam

CrossFit Tay Ho is an established Hanoi training community that has entered a new phase in 2026. The legacy Travel S Helper record points to 34 Đặng Thai Mai, the address still shown in the global CrossFit affiliate directory, but the operator's current website now redirects to UNDRGRND Athletics and explicitly calls the new facility “the new home of CrossFit Tay Ho.” The opening material gives the new address as Basement Level 2 of Lion Mall, 59 Xuân Diệu, Tây Hồ. A current TeamUp membership page also uses the combined identity “UNDRGRND Athletics (Home of CrossFit Tay Ho),” so this is best treated as a rebrand and relocation of the same Hanoi CrossFit community rather than as a vanished business or a different entity.

For visitors, the most important practical change is therefore the address. Do not navigate to the older Đặng Thai Mai pin simply because it still appears in the official CrossFit directory. The operator's 2026 opening page announces the Xuân Diệu facility, and the timing is unusually easy to date: it promotes an August 22 grand-opening morning followed by an August 24–30 trial week that TeamUp explicitly dates to 2026. That newer evidence outweighs the lagging affiliate address. Lion Mall is in the West Lake area, so the gym remains in Tây Hồ, but the arrival point is now a commercial-building basement rather than the former standalone location.

The training identity remains CrossFit at its core. The current operator describes coach-led 60-minute CrossFit classes built around functional, constantly varied and relatively high-intensity work, with scaling for different levels of experience. Its service list also includes BUILD 60 for strength and hypertrophy work, a Barbell Club focused on Olympic lifting and powerlifting movements, and SWEAT 60 for endurance-oriented, barbell-free training. That broader schedule helps explain the UNDRGRND name: the facility is no longer presented as only one CrossFit class format, although CrossFit Tay Ho remains central to the community and brand story.

Travelers who already have CrossFit experience can book a drop-in. The current visitor page lists a single-class drop-in and a one-week unlimited option, and TeamUp continues to sell visitor passes under the CrossFit Tay Ho name. Short-term visitors should not use the resident free-trial route; the operator specifically says its free Saturday Team WOD is for people living in Hanoi for at least two months. That distinction matters because a tourist arriving without reading the booking rules could otherwise assume the free trial is a general first-class promotion. If you are only passing through Hanoi, use the dedicated drop-in booking channel.

Beginners need a different pathway. The operator says new members normally start with an Essentials Course consisting of two 90-minute small-group sessions covering foundational movements, technique and terminology. The page also states that the course normally runs on Mondays and Wednesdays at 19:00, but the broader weekly class timetable is handled through live booking rather than a simple static opening-hours table. For that reason, this record does not publish the former Đặng Thai Mai class hours as though they still govern the new venue. Check the live booking schedule for the specific day and class you want.

The new-facility launch emphasizes more than workout floor space. Current UNDRGRND material describes coaching, community and a facility intended to support training before and after class; the older CrossFit Tay Ho about page also describes open-gym access, showers, changing areas, a treatment room, café space and an ice bath. Because the operator was in the middle of a 2026 move and expanded schedule rollout, confirm which amenities are fully available at Lion Mall rather than assuming every feature of the former facility transferred unchanged on day one.

CrossFit is physically demanding, so visitors should be realistic about recovery and experience level. A drop-in is most appropriate for someone who already understands the movements and can tell the coach about injuries or limitations. Newer athletes should use the coaching pathway instead of treating the session like an unsupervised tourist gym visit. Bring training clothes, appropriate shoes and water, arrive early enough to meet the coach, and follow the operator's request for drop-ins to arrive about ten minutes before class. If you have a recent injury or a medical condition affected by vigorous exercise, obtain appropriate medical advice before high-intensity training.

The strongest reason to keep this legacy entity active is continuity: CrossFit's own directory still recognizes CrossFit Tay Ho as an affiliate, while the current local operator, current TeamUp memberships and 2026 opening campaign all connect CrossFit Tay Ho to UNDRGRND Athletics. The correct visitor-facing interpretation is therefore not “CrossFit Tay Ho closed,” but “CrossFit Tay Ho moved and broadened its identity.” Use 59 Xuân Diệu, book through the current UNDRGRND/TeamUp system, and verify the live class schedule rather than relying on static hours from the old Đặng Thai Mai location.
