I used to be a very fit endurance runner. I took up weight training 3 years ago to gain strength ontop of fitness. I have continued tio run at least twice weekly but only short distances. Now i cant get 50mtres without gasping for breath. I cant run 5km without stopping at least 6 times. Whats going on? Ive been doing some interval training which is ok because i have active rest times, but i cant manage anything continuous like i used to. I am very strong in the gym with bodyweight training ie lots of chinups etc and i lift heavy weights. I am 42 yr old female and weigh 54kg. Please help, its embarrasing!
