I’ve heard that significantly exceeding your target heart rate during aerobic activities can have a detrimental effect (possibly stripping you of muscle and or retaining more fat)
I am currently weight training four times per week (one day on one day off ie, mon,wed,fri,sun) in the afternoon/eve and doing 30 minutes of cardio at my target heart rate for my age and weight five to six mornings a week in addition to following a six meal a day “glycemic index” type diet in an effort to gain/retain muscle while losing fat and generally increase my cardiovascular health.
