Short answer
Smart Fit Del Sol, Athlon and Premier Asunción publish enough information for an initial gym shortlist. Smart Fit lists a no-commitment plan at ₲229,000 a month plus ₲199,000 annual maintenance; Athlon lists several formats whose scope needs checking, and Premier's page does not load a price. We have not checked equipment or staff in person, so we assign no ranks. Sources checked September 26, 2026.
The Aviadores del Chaco branch lists 6 a.m. to 11 p.m. Monday through Friday, 9 a.m. to 6 p.m. Saturday, and 9 a.m. to 3 p.m. Sunday and holidays. Its Smart plan is ₲229,000 a month with no commitment, free enrollment and ₲199,000 annual maintenance. The same page describes a Black plan with a 12-month commitment while also saying there is no minimum stay. Request the actual contract before choosing that plan.
Athlon lists Cerro Corá 527 near México and says it charges no enrollment fee. Its site shows ₲150,000 for a 'clase individual', ₲500,000 for 5 months and ₲1,000,000 for 12 months. The first label and 'de mes a mes' description do not clearly establish whether ₲150,000 buys a month of access. Ask for the duration, hours and included services in writing.
Premier places its branch at San Martín and Sucre in Paseo Los Árboles. It lists 5:30 a.m. to 10:30 p.m. on weekdays, 8 a.m. to 8 p.m. Saturday and 9 a.m. to 1 p.m. Sunday. It advertises daily and monthly plans without enrollment, plus showers, lockers and parking. The packages section did not display prices on the page we checked; ask for the final charge and terms before traveling.

- Add 12 monthly fees, annual maintenance, enrollment and time-limited discounts. A first-month promotion does not show the annual cost.
- Confirm the branch, your training hours, included classes, cancellation terms and payment method before signing.
- Visit at the time you would train to check crowding, upkeep and equipment. Operator pages cannot replace that check.
