i didnt really read any of the replies. but ive made amazing gains since i was 15 and started mixed martial arts. im 21 now, and i weight 158 lbs on average, i fight at 145, and im 511.
in my opinion, start with 2 25 lb dumbells, and a barbell and some weights.
do these workouts on one day. 4 sets times 7-10 reps. explode up, go down slow. before you do this workout, shadowbox(or do the bas rutten tapes!) for 25-30 mins, as well as LEARN HOW TO JUMPROPE. and then start your lifting.
dumbell curls+hammercurls(5each, do a curl and hammer curl on one arm, then the next;thats one rep.
barbell shoulder press+bent over row(do 5 shoulder press, then without dropping the weight, 5 bent over rows.
bench press+elevated push ups(5 bench, five push ups, you get it.)
dumbell overhead squat+barbell deadlift
dumbell lunge+dumbell box step up
finish the day with some STRETCHING and a light run or some more shadowboxing or pad drills. take 50 grams of protein an hour before, and 50 grams 30 mins after. aswell as once when you wake up. id recommend one more rep or some kind of pre workout, but dont start drinking it til your down with the cardio at the beggining. inbetween your sets, wait a minute and a half. keep it simple like this and after 2 weeks youll understand your body enough to know what to look for next.
good luck. hope you try it out.
