After intense training, muscles tighten and circulation to fatigued tissue drops. Heat dilates blood vessels and boosts blood flow, delivering the oxygen and nutrients that speed recovery and flush out the by-products of hard exercise. Warmth also relaxes tight muscles, improves range of motion and loosens stiff joints before a session — making heat useful both as a pre-workout mobility aid and a post-workout recovery tool. Use ice for acute swelling or injury; use heat for soreness, stiffness and chronic tightness.

• hCore X-L — large pad for the back, hamstrings and big muscle groups after lifting
• hCore Knee — wraps the knee joint for runners, lifters and jumpers
• hCore Neck — eases shoulder and neck tightness from pressing and overhead work
• hCore X — targets specific sore spots and smaller muscle groups

• Post-workout muscle soreness and DOMS recovery
• Loosening stiff joints before training
• Knee warmth for runners and cyclists
• Lower-back recovery after deadlifts and squats
• Shoulder and neck relief from pressing movements
• Staying loose on rest days

For recovery, apply heat for 15–20 minutes to the worked muscle group a few hours after training or before bed. To loosen up beforehand, use a short warm application before your dynamic warm-up. Keep heat comfortable and steady, and listen to your body — if a joint is acutely swollen, ice first.

Every hCore device is made in India to ISO 13485 medical-grade standards with even heat and auto-cut safety — built to handle daily recovery use.
