Hello Brandon!
It is OK to do this as long as you work in slow to semi-slow motion. DO NOT try to do any fast hitting or kicking with weights. If you do, you are in danger of hyperextension or other damage to your elbow and knee joints. In this case slow is very good, but fast is VERY BAD! Be careful using this training method, do it right (right being slow and controlled movement), and you WILL see good results!

Keep Blasting!
