I have started using the gym cardio equipment to train with a heart monitor. I was wondering what is the most effective heart rate to burn fat and increase fitness. Secondly what is the best cardio equipment for rugby fitness, treadmill, Bike, sitdown bike, rower, crosstrainer? I live in a place where there isn’t room to train properly outside so the gym is my only option. Thanks for your advice.
