Hey, so I've been strengh training for a while now, and I've noticed that I've reached the point where the max weight on the dumbells I own is not enough to completely fatigue me on those last reps on some excercises (specially lower body), which is awesome! but right now I can't buy new weights. My goal is to continue building lean muscle so my question is can I do that by fatiguing my muscles with some HIIT, and then using weights? Since the muscles are already tired from the HIIT portion I can't lift as heavy, but I don't know if I'll still be building muscle with this strategy. I hope someone can help!!
