If you can, I recommend having a protein shake after your weightlifting and before your cardio as this will help mitigate the muscle breakdown. HOW OFTEN YOU SHOULD DO CARDIO In terms of frequency, here’s how I do it: • When I’m bulking, I do two 25-minute HIIT sessions per week. • When I’m cutting, I do three to five 25-minute HIIT sessions per week. • When I’m maintaining, I do two to three 25-minute HIIT sessions per week. • I never do more than five cardio sessions per week, as I’ve found my strength begins to drop off in the gym if I do.
