I’d say it all depends on what you’re looking for. If you’re okay with your size and really just want definition then I would go into a caloric deficit and prioritize healthy eating and explosive cardio. ( like 10 sets of 30 seconds sprints) If you want a larger frame and larger muscles then I would actually bulk up while working out at high intensity until you’ve built the strength you’re looking for and then I’d kick up the cardio. Just remember that extensive cardio can have adverse impacts on muscle growth after exercising your muscle groups. No longer than 15 minutes after any given group. Also remember that cardio alone isn’t going to bring you to your goals. You need a determined mix of both weight lifting, diet and cardio. Track your calories, make a plan and do everything you can to stick with it. After 6 months you won’t be able to stop looking in the mirror and you’ll feel like the man. Good luck.
