Hello girls, I am a 42 years old man and I am using RLT to ease muscle pains and it is doing it’s job nicely. I do not do workouts or exercise but I normally jog every morning for about 50mins to 1hr and ever since I used RLT I get to complete my daily task after I jog unlike before. So, I guess it is safe to say that, yes! RLT will help your kids especially they are physically active.
