If you’re reading this you should probably be lifting weights. Nothing will have as profound an impact on your physique, body fat levels, and overall health as resistance training (besides nutrition of course!)
How should your training change when you’re in a dedicated calorie deficit? The first mistake I see is reducing the amount of lifting and increasing cardio to an unnecessary amount. Adding 3-4 HIIT sessions, going on runs when you never would run before, and adding purposeless movement for the thought of burning more calories.
