Kind of depends on what you consider as your warmup....we start with a dynamic warmup. Hi knees, hi knee crossover, karioca, high knee karioca, and some additional plyos.
We dont throw until about 45 minutes into practice. Now our throwing warmup starts at 20 ft on one knee, then backs up to 45, 90, 120. Kids are in athletic stance moving to each throw, simluating our 2-step release on every catch, then regroup and throw (at 90 feet and remaining until we bring it in to 45 ft to end we catch and immediate 2-step release to throw). By the time we finish our kids have a good lather and are a little winded.
After our dynamic warmup we have Var/JV on field working baserunning at all bases with a hitter executing a hit and run. All runners working reads (r1 steal/H&R, r2 gb behind, in front, tagging on fly, reading ball in gaps, r3 contact play/sac fly, hitter gets one pitch h&r) We time our guys running to first and post at end of practice (accountability for hustle. can't run a 4.2 and 4.7 and say you hustled). At same time freshman are on side field working 4 bunts, then we switch.
After this we go to individual defense, team defense, situations. (Bullpens being run during all of this)
More than you asked for but was unclear as to "warmup".
