>>76300364Think about it anon. You'll need every part of your body taut and tense and ready for anything and everything. What if the person you need to kill is a decent fighter? What if he or she is a good runner? What if it doesn't go as planned and you need to utilize something else?
There's also the cost of such strenuous exercise too with food, protein and supplements(because food wont be enough) and getting decent rest. I have my own routine but if I was going to do what OP wants too, and also basing off my own experience in the gym, that's the routine I personally would do. Learning basic fighting techniques would also be a must.
