My left hand is slower than my right hand how can i speed them both up
You could try typing more words like 'taeradcw' and 'scfgadrtwqw'. These words would improve speed and coordination of the left hand more than the right hand though.
If You speed both of them up, then, Your left hand will still be slower than your Right...
It's slower? WHat's that supposed to mean?
start use ing your left hand more and then start use ing them both
Get some 10 lb. weights to lift, do as many curls as you can in a min, do three or for rounds of this every day. It will increase your whole arm speed.
