An ideal cardio session should be around 45 minutes. If you lift weights before aerobic training, youâll only need 15-20 minutes of cardio. Youâll get the same benefits as you would do in 45 minutes without weight training.
Iâm around 7% body fat and I got here doing about 1.5 hours of cardio per week (in addition to my weightlifting of course), and I maintain this look more or less year round doing 45 to 60 minutes of cardio per week. train 6 days/week (1 day with a trainer) and currently do 2.5 hrs. of cardio/week (30 minutes/day)â¦think Iâm going to be changing my routine. Thanks for the information Mike. Thanks! Cool on your stats and youâre going to lose weight if you want to go from 11 to 7%.
