Below are just some of the reasons why Krav Maga classes at IKMF Singapore will benefit you. 1\. There are no rules in street attacks\, so imagine what we will do to the attacker\. 2\. No one wants to get in a fight\, so prevention & de\-escalation will be taught too\. 3\. You're lucky if there's just 1 attacker out in the streets\. To better prepare yourself\, we train with the mindset of potentially facing multiple attackers\. 4\. Did I mention weapons? Who says attackers can't possess knives/sticks/guns? ### **Address** 767 Upper Serangoon Rd, #01-05, 534635 Singapore (Kali Majapahit Martial Arts studio) ### **Schedule** Saturdays 4PM - 530PM ### **Booking Information** * Please contact **98225900** to find out how to book this class. * The instructor will reach out to you once you've booked the class.

Hello everyone! This is a challenge walk where it is more than our usual walks of 15km and only open to people that has joined us at least thrice! The plan will only be revealed in the whatsapp group chat! The route may be modified during the walk to better suit the group’s pace and fitness levels. The organizers will make adjustments as needed to ensure the walk remains enjoyable and manageable for all participants. Do drop me a message via whatsapp or via meetup if you will be late. You may consider the following: 1\. Comfortable Clothing • Moisture-wicking fabrics: Avoid cotton, as it traps moisture and causes chafing. Instead, choose clothing made from materials like polyester, nylon, or merino wool, which keep you dry. • Comfortable socks: Opt for moisture-wicking socks with cushioning to reduce the risk of blisters. 2\. Proper Footwear • Well-fitting shoes: Ensure your shoes are properly broken in and provide enough support, especially if you're walking long distances. Sturdy hiking or walking shoes with good arch support are ideal. • Blister prevention: Consider blister-resistant socks or pack blister pads to address any discomfort before it becomes a problem. 3\. Hydration • Water bottle: Stay hydrated throughout the walk to maintain energy levels and prevent dehydration. 4\. Snacks • Energy bars or trail mix: Portable, nutrient-packed snacks high in carbohydrates and protein—perfect for refueling during breaks. • Nuts or dried fruit: Easy to carry and great for providing long-lasting energy. 5\. Umbrella • Umbrella: Bring one in case of rain to stay dry and comfortable. 6\. Optional Gear • Tissues or wet wipes: Handy for personal hygiene or cleaning your hands after eating or drinking. 7\. Small Backpack or Waist Pack • Use a small, comfortable bag to carry your essentials. Ensure it fits snugly and doesn’t rub or chafe over time. Disclaimer:
