Interleave Training is a type of training has been around for decades. You may have heard about it as varied or mixed training. It seems that this training works by interrupting each skill with a different skill and then forcing your long-term memory to then go back and access the first skill over and over.
In traditional block training we take skill/task A. We train them by performing A thrity times. In interleaved training we would perform task A, then task B, then task C once each. Then we would repeat that three times.Block training is AAA then BBB then CCC, interleave training is ABCABCABC or ABCBCACAB (never repeating the same skill back to back).
This type of training has been proven to work by making your long-term memory recall faster when tested at a later date (WARNING, you need to already have the tasks in your long term memory for this to work. Don’t do this with brand new skills.) Mixing up two or three tasks during one practice session allows you to remember/perform each of the tasks at a higher level at a later date. Oddly enough you will actually perform the tasks at a slower/lower level during that practice session but will improve on testing at any later date.*
An example of interleave training is, practice a slow but technically perfect unload procedure. Then practice a slow technically perfect draw to your practice target. Then practice a slow technically perfect trigger press with sight alignment but no sight picture(no target just a blank wall). Then repeat that sequence several times. As you improve your speed in each task/skill you can also vary the speed of completion as well as the actual task. i.e. draw to on target at your fastest speed, then do a slow reload and then study one state statute. The idea is to change-up the skills making your mind break its rhythm. The more different the skill the better the interleave training works.
This also works during live fire. Fire your course of fire quickly from 5 yards on a 6 inch target. Set the gun down. Pick it up and perform a tactical reload. Put the gun down. Pick it up and fire slowly on a dot trying to knock out the dot with perfect aim.
*As you start using interleave training and you start testing, do any testing at the beginning of the practice session. This allows you to track progress from session to session.
