Hi everyone
I'm 51 and for the past 6 or 7 years I have been running twice a week and strength training 3 times a week. I love running. I'm not brilliant at it but usually manage 5 km in around 30 minutes. Increasingly I am noticing that I have lower back pain after I run. Sometimes I feel a jarring while I am running. A few times it has fully 'gone' and led to 3 or 4 days not being able to move at all.
I wear good trainers, stretch and have done lots of Pilates but nothing seems to help. If I run very slowly it hurts less but then I don't feel the cardio benefits.
I'm wondering if I should accept that I'm older and move to something like the Stairmaster for cardio. It would be a shame as it would involve traveling to the gym on extra days and I would miss the fresh air but I do want to maintain cardio a couple of times a week.
Does anyone have any advice? Does a Stairmaster burn as many calories as running?
Thanks
