U.S. Karate & Boxing
Karate, boxing and fitness classes for kids, teens and adults in Hayward, on the mat since 1984.
Acerca de
For more than four decades a Hayward karate school has been teaching children to bow onto the mat, and today it trains under the name U.S. Karate & Boxing. The chamber's directory still carries the older name, US Karate School, and an old storefront at 20613 Mission Boulevard. The gym's own website now gives 1671 Industrial Parkway West, in south Hayward, as its home. Joe Olivarez is the owner named in the directory record. Because listings disagree after the move and the rename, confirm the current address and phone before a first visit.
Classes on the schedule
According to the gym's website, the programme mixes three things: traditional karate instruction, boxing training and general fitness classes. Sessions are arranged for children, for teenagers and for adults, so a parent and child can train in the same building, often back to back. The site dates the school to 1984, the same founding year the chamber's records show.
Some third-party listings also mention kenpo, kung fu and self-defence work. The gym has not confirmed those here, so ask which styles are taught now and at what levels.
Starting as a beginner
Watch a class before you sign anything; a good instructor will welcome it. Ask how students are grouped, by age, by belt or both, how often belt tests happen and whether they carry a separate fee, and what gear the first month calls for, such as a uniform, gloves, hand wraps or a mouthguard. For children, ask how many instructors are on the floor per class and who teaches when the head instructor is away. Read the membership agreement for its length and cancellation terms before paying, and ask whether a trial class is available.
Hayward and nearby
Industrial Parkway runs through the southern end of Hayward toward the Union City line, a short drive from the South Hayward BART station. That puts the gym within reach of Union City, Fremont and Newark to the south and of Castro Valley, San Lorenzo, San Leandro and Dublin to the north and east, all in Alameda County.
The directory number is 510-317-8825. The gym's website lists (510) 561-5029, so if one line does not answer, try the other.

Preguntas frecuentes
Típico de este tipo de negocioWhat age can children start martial arts?
Many schools take children from about four or five in short, play-based classes, with regular classes from six or seven. Ask the gym how it groups young students and whether a parent needs to stay on site during class.
Do I need to be fit before my first class?
No. Beginner classes are meant to build fitness gradually. Tell the instructor about any injuries or health conditions before you start, drink water, and expect to be sore after the first week or two of training.
How long does it take to earn a black belt?
It varies by style and school, but four to six years of steady training is common. Ask how often belt tests are held, what each rank requires, and whether testing is included in membership or charged separately.
Is boxing training safe for teenagers?
Most gyms teach technique and conditioning on bags and pads long before any sparring. Ask when sparring starts, whether it is optional, what protective gear is required, and how closely coaches supervise it.
