Haumoana Jiu Jitsu/Grappling is a club at 50 Haumoana Rd, Haumoana, in the Hastings district, with a Google rating of 5.0. By its name, it teaches jiu jitsu and grappling.
A good martial arts club is welcoming, safe and well run, with instructors who teach technique and control, not just strength. Jiu jitsu and grappling are close-contact arts that rely on leverage, holds and escapes, so a good club starts beginners with the basics, pairs them with careful partners and teaches how to "tap" to stop a hold. Ask whether you can try a class, what to wear, since many clubs use a gi or fitted sports clothing, and how classes are structured by age and level. Keep nails trimmed, remove jewellery and tell the instructor about injuries. Regulars train consistently, a couple of times a week, keep their gear clean, look after their training partners and stay patient, since progress takes time.
For people in Haumoana and Hawke's Bay, Haumoana Jiu Jitsu/Grappling is worth contacting about trying a class.
