Well I would just like to say ladies, over the years I have been to the gym on and off tried running/jogging always been active even at my heaviest 24 st 11 I went to Zumba and could dance the night away. I recently watched a program I don't know if any one saw it or not bout 50 rules for a health body diet and exercise. Well the exercise was quite worrying, the health experst are encouraging people to walk more as people who run regularly and do Zumba and aerobics and gym work are all after some time showing signs of wear and tear on knee joints and hip joints, torn ligaments, torn muscles etc. People are getting joint replacements and repairs younger and younger because of the impact of this exercise. It referred abck to yes trainers are padded thye can damage our feet and apply pressure yo calves etc. The constant pounding on the joints is really damaging, as is the no pain no gain saying. The body is being punished and cannot cope and so things begin to go wrong, the heart is being put under increased pressure and heart attacks are becoming more common also as healthy eating is not taking place and then they go to exercise and dont realise arteries are becoming blocked hence heartattack. IT WAS ON FOR 2 HOURS was amazing really, very eye opening. Don;t think I will be going back to gym AFTER WATCHING THAT. Just food for thought and we all have our own opinions just thought would play devils advocate xx Hope you don't mind xx
