I have been working out on my treadmill. I could only run for 1min and walk 5min. But i have worked myself up to running 30 min on a hill incline of 2 which i am very proud off. I just got a Women s health and fitness mag and they suggested that you should be doing interval training! so for the last 2 days i have been running at 8km for a min then back down to 5.2!, and i do this for 30 mins as well i do find i get a harder workout and sweat alot more. My question is would i benefit more doing interval training 3 days a week with my regular jogging or just stick to my normal routine which is normally just jogging and weights??
