arts power

Will doing my martial arts techniques and forms with weight straps help me in any way? I.e with power or speed
I see these weight straps that runners and aerobic people use. If I use them during my bag sparring and technique/form practice or hold a set of dumbells while executing punches or something will I reap any benefits? If so what?
No. You need to “feel” each technique as you do it over and over thousands of times.
In a “real world” situation, you won’t have weights on your arms and legs.
I’d do resistance exercises (weight training) for strength, but leave your martial arts techniques alone.
