Hey guys, I'm a beginner in fitness and I'm trying to improve my endurance and stamina for longer workouts and events. I've recently signed up for a charity run and I'm struggling to keep up with the training schedule. I get winded easily and have to take frequent breaks. I want to build up my endurance and stamina so that I can complete the run comfortably without feeling exhausted. What are some tips or exercises that can help me build up my endurance and stamina? Any advice and suggestions would be really helpful. Thanks in advance!
