Sometimes, especially when the horse is not forward (first rung in the training scale) you must do this - idea is get them forward then STOP the "nagging" legs, because if you don't stop nagging they eventually start ignoring you and things get worse. Sometimes the riders lower leg is so "loose" it appears to move quite a bit - but is in fact moving up and down rather than into contact with the horses barrel.
With my mare I may alternate to get her going but if she start to quit MARCHING forward (at the walk) after that I bang her HARD with both legs, then go back to asking nicely. The thing is once you bang the horse they may leap forward and you can NOT use the reins harshly or abruptly to slow them back down, you must reward them for listening to the FORWARD command, then bring them back to the walk.
But legs should drape around the horse and lay next to their barrel quietly unless you need to use one or more - for lateral work, straightening, etc.. What the OP is seeing with the nagging legs is the rider striving to get the horse MORE forward every stride (especially at shpws when you want 100% from the horse), but in actuality they're making the horse duller to the legs
. As an upper level rider I ask once nicely then if no reaction demand once, then return to a neutral zone until I need to direct the horse again. All my horses have LOTS of gas in the tank (it wasn't always that way) and do NOT need constant nagging with leg, spur and/or whip.
