You sacrifice some, but my goal is to cut not improve my lifts at the moment. Plus when you get your heart rate up really high you release a lot more GH durning and post exercise. Which means hopefully more fat utilization and better recovery.
So my program will look something like this.
Bench:3x10
Tabata: stairstepper 2min
Incline press: 3x10
Tabata: Mountain climbers 2min
Chest flies: 3x10
Tabata: stair stepper 2min
And so and and so on. So by the time I’m done lifting I’ve got 20-26 minutes of HIIT done (cardio) and my heart rate is elevated into my desired range the entire workout. Which I want to be in the 130’s the entire workout. Then when I’m done with weights I will do 15-20 minutes steady state cardio to cool down and burn a bit more muscle glycogen off.
Here is a sample of what my heart rate looks like through my workouts.
