since u r just starting out your gonna probly want to just start with basics....join a boxing gym for inperson training...... basically learn the proper form witch is different with each teacher but i personal use a left lead since im right handed...never b square....work all the punchs....get your jab fast not powerful...get your str8 fast but strong.....fight under control never lose your mind and swing wildly...teach your body to be able to through punchs automatically without even thinking about it..... shadowbox as much as possable..... do pushups, pullups, and sit ups, use weights only to improve strength and after hold dumbells in your hands and throw punchs to increase speed... at first though dont try to go fast and hit hard just get all the punchs down perfect and always try to keep your form until u have it near perfected.....hope this helps at all if u have ne questions ill try to help seeing as i personally train everyday
