Hey Tav ive been doing brisk cardio about 4-5 days a week for 20-30 mins this offseason/bulk and im loving it bro.. staying way leaner/vascular and the size/strength is increasing at a good rate(not as fast if i was eating more and doing less cardio, but still increasing good)..... so far at around this time im happier then last year when i did barely any cardio... i have a feeling ill be wearing tank tops and veining out like a mofo all winter long!
