Extend all of ur punches when ur shadow boxing. Step into the jab. Wait until u become VERY experienced before u make that type of defense ur main one. Train with both hands held high. Try to throw ur punches efortlessly/fluent. Don't throw 1 or 2 shots at a time (on the heavybag or anytime). Keep'em in combinations. U look like ur doin alot of thinking about what ur looking like before/during throwing ur punches. Just react. Ur game will come along if u only worry about training & reacting (using good basics) & not what u look like. Keep training & good luck.
