I am getting into the home stretch of my cutting phase and I am looking to increase the amount of times that I am doing cardio each week. I am currently hitting my legs hard twice per week on the weights which is leaves them sore for most of the week. I am finding that on most days my legs just cant cope with high intensity cardio such as sprints or kettle-bell movements.

How can I increase my cardio frequency and/or intensity without compromising on my weight lifting? Do I just have to abandon the high intensity cardio and switch to moderate intensity steady-state?
