Add cardio bursts

To give strength workouts more of an endurance edge, Gabi Garbarino, CPT, founder of Gabi’s Fitness Studio, recommends adding cardio bursts into the mix. “I love to incorporate jump squats, jump lunges, mountain-climbers, and pretty much any short cardio burst that involves spiking the heart rate,” she says. Not only does this train your cardiovascular endurance by keeping your heart pumping, but also demands that your muscles keep working between sets of other exercises.
