Advice gratefully received...I'm 37, and exercise for an hour 5 times a week (run for 40 mins 3-4 times per week plus stretching, and do yoga/weights class 1-2 times per week). I've built up the running over the last year from nothing, though I've always been a gym bunny, and outside my office job I am fairly active - walk and cycle rather than use the car. I'm lucky enough to have more time over the summer and would like to do more exercise but find I'm too tired to do more than I'm doing. Gets to Wednesday, and my legs are wobbly; even pilates/yoga feels too much. If I don't have a rest day on Wed and at least one at the weekend my running slows and I find any form of exercise really hard.
So two questions to you exercise experts (or enthusiasts, or just anyone kind enough to bother, frankly): firstly, is the amount of exercise I'm doing now enough (I'm at my ideal weight and I feel good on it)? Secondly, any tips for how to up the tempo - ideally I'd like to do some form of cardio 5 days per week whereas at present I'm doing 3-4. Thanks a lot!
