The addition of cardiovascular exercise to a strength training program is often criticized in the strength community due to the potential interference effect, which can limit strength gains. However, it's important to consider that most studies on concurrent training involve extreme conditions. Several factors can moderate the interference effect, such as frequency and duration of the cardiovascular exercise. More frequent and longer duration cardio tends to have a greater impact on reducing strength gains compared to less frequent and shorter duration cardio. In addition, choosing cycling as a form of cardio appears to be the best option for most lifters as it can induce lower limb hypertrophy according to some studies. To minimize the interference effect, cardio should be performed with low volume and with 6-24 hours of rest between types of training and should be limited to about 3 times per week. Moderating these factors can help to minimize the potential for an interference effe...
