Hi Everyone,
I have only gotten modest results over the years in fitness.
When I trim down, I tend to lose my strength and muscle, along with my fat. I have done plenty of running, treadmill, exercise bike, etc. Yet, it only seems to make hip-flexors and hamstrings tighter, without really trimming down.
What types of cardio can get a person more fit, without losing muscle? Any research to support such conclusions?
My guess is real-world stairclimbing (not stairmaster), wind-sprints, etc. is the best.
