Hello folks, so as the title says, i've got a problem with my right hamstring, but still don't wanna miss out on cardio at all. My goal, so as long as i'm injured, is to just maintain or maybe slightly increase my aerobic cardio. Is there a cardio exercise (which i can do for 45-60 minutes) that does not involve the hamstrings in the slightest? If not, then is it sufficient to to just shorten the breaks between my strength training exercises*, to increase the intensity for my cardiovascular system? Is that maybe even the preferable option for me to a possible separate cardio exercise? *(currently doing mostly push ups, leg raises, pull ups and a few dumbbell exercises) Thanks in advance to y'all.
