Lower Body Strength Training

July 8, 2016
If you would like to be fast, you need to strengthen your lower half. We all know the bro at the beach who only trains upper body and has small legs (don’t be that guy.)  Today I will outline some lower body strength training exercises and progressions that I would recommend.  I have all of these exercises listed on my Youtube page. As an athlete, it’s important to train bilaterally and unilaterally, or exercises on two legs and one leg.  It’s also important to perform plenty of sprints or loaded sprinting exercises in addition to your general strengthen. The below progression will begin with the most basic exercise and progress to the most difficult. Lunges/ Single Leg Squats When performing any lunging variations, it’s important to remember to control ankle, hip and knee alignment. When performing a lunge, be sure to maintain a neutral spine, and move your hips, knees and ankle joints in. DB Goblet Split Squat Lunge->DB Reverse Lunges ->DB Step Ups->DB Forward Lunges->DB walking Lunges->DB Rear Foot Elevated Split Squats->1 Leg Squats to Box->1 Leg Skater Squats Hip Hinging Hip hinging is shifting your weight back while maintaining a neutral spine and a vertical shin.  When hip hinging, it’s important to make sure you’re not rounding your back or losing a neutral spine position. Below I will outline some progressions for hip hinging.  If you cannot touch your toes, I do not recommend deadlifting. KB Deadlift-> Trap bar Deadlift->Barbell RDL->KB Swings->Barbell Sumo Deadlift->Barbell Conventional Deadlift 1 leg Hip Thrust off Bench->1 Leg Cable RDL-> 1 Leg DB RDL-> 1 Leg Barbell RDL Squatting Squatting is another fantastic movement to help strengthen the lower body.  Learning to squat is about creating full-body tension through the hips and core.  When squatting, think about spreading the floor apart and screwing your feet into the ground.  It’s also important to keep your upper-back tight, so don’t flex your spine when squatting. Below I will outline some squatting progressions. DB Goblet Squat->Barbell Front Squat->Barbell Box Squat-> Barbell Back Squat Sprinting When training the lower body to get stronger, it’s important as an athlete to incorporate sprinting and loaded sprints.  When training with sprints, it’s important to run as fast as possible or you won’t get faster. Body Weight Sprints-> Sled Pushes-> Sled Sprints->Reverse Sled Drags To wrap up the lower-body training session, here is a sample program. A1. Trap Bar Deadlift 4×3 A2. Db Reverse Lunge 3×4/leg B1. Barbell Front Squat 3×4 B2. 1 Leg Hip Thrust off bench 3×5/leg C1. 1 leg Db RDL 3×4/leg C2. Sled Pushes 2×20 yards

MSI Pro Athlete Update

June 6, 2016
During the winter, you can routinely find a group of athletes affectionately known as “The Crew” training and preparing for their seasons with MSI’s Rob Rabena. These guys have become a staple of the culture at MSI and its their work ethic and dedication that sets the bar for all other MSI athletes. Now, with their seasons underway, we provide an update on members of The Crew and see how they’re doing after an offseason training with The Legend, Rob Rabena. Josh Ockimey (Twitter – @josh_ock) (Boston Red Sox) Playing for Single A Greenville, “Ock” is off to a tremendous start at the dish, batting .305 with 9 HR, 29 RBI, while also working out 42 BB en route to a .445 OBP. Tim Mayza (Twitter – @Mynameis_TmAyz) (Toronto Blue Jays) Starting the season with High A Dunedin, Mayza has been nothing short of lights out, pitching 29.1 innings, with 36 K and 3 Saves, while producing a miniscule 1.53 ERA. Harrison Bader (Twitter – @aybaybader) (St. Louis Cardinals) A Cardinals’ Double A prospect, Bader has simply been destroying baseballs, to the tune of a .318 AVG, with 11 HR and 27 RBI in 50 games played thus far. *Stats as of 6/2/16

Softball Success: Master The Turn Over Drop Pitch

June 1, 2016
Like the changeup, a good drop pitch can serve as an off-balance tool in a pitcher’s arsenal because it creates doubt in the batter’s mind as she tries to guess what’s coming next. More importantly, the drop pitch is effective at creating swing-and-miss strikes. When the ball drops several inches as it approaches the plate, the batter generally swings over the top of the ball. At the very least, an effective drop pitch causes the batter to hit only the top portion of the ball, typically resulting in an infield ground ball. That said, the drop pitch serves as an effective “out” pitch whether trying to induce a double play or getting out of a bases-loaded jam. So, how can softball players master the drop pitch? Maggie Kichler, MSI’s Director of Softball, explains below. Turn Over Drop Pitch Hard snap down and staying tight into your hip Push up off the mound instead of out Four-seam rotation downwards Weight should be shifted forward Straight down with snap and not across body The name says it all – a drop pitch should appear to be coming straight, but dip down before it reaches the batter. This forces the batter to start thinking much more strategically than when she faces a straight pitcher. The drop pitch combined with fastballs and changeups will play mind games with the batter, leading to strikes and forcing mistakes as she tries to anticipate the ball’s movement. Like the changeup, the movements preceding the drop pitch should mimic the set-up for a fastball. Stay tuned for the next installment of our pitching series. Later, we’ll discuss the peel drop and its importance in a pitcher’s arsenal. Do you have something to add to the turn over drop pitch discussion? Share with us on social media and comment below!


Maggie is great! She is unbelievably supportive and very knowledgeable, explains things great & my daughter just adores her!

Dalton, my wife and I are really happy with the whole experience we had. We really liked Coach Stumpo and what he was saying. My son was all smiles and talked about his lesson the rest of the night. We are DEFINITELY coming back. I have to tell you that my son seemed invigorated about baseball again.

Chris Sweeney, MSI Parent

We are grateful for the experience that Ethan is getting and appreciate all you and the other coaches do for the kids. You guys are very good with the kids run a great program.

Crissi, MSI Parent

We just wanted to thank you for all your help with Jonathan. Today on Super Bowl Sunday Jonathan verbally committed to the Golden Rams of West Chester. Their coach was very excited about his commitment and sees him as one of his top guys for the next four years. The MuckDawgs program has been a great experience for Jonathan right from day one, verses where we came from. Jonathan has worked hard right from the start when you told him to fill out his jersey. You have given him the tools he needs to be successful on the field and in life. We are very thankful for all your help!

Brooke is throwing her change-ups and they are working big time! The girls were way ahead of the pitch. Brooke could not stop smiling!
Nice work coach!

Scott, MSI Parent

Thanks for putting on a great clinic and for the hospitality of Maple Zone.
Max is benefitting greatly. He was very excited to have gotten 2 FO wins using the fish hook technique the other night. It is great stuff. You are turning him into a student of the game and have opened up a new world to him.
Great job and thanks again.

Mark, MSI Parent

I wanted to thank you again for putting on a great winter lacrosse league. This was our first year in your league, and it was the best winter league we have played. We will definitely be participating next year.

Jeff, MSI Parent

Service at Maple Zone scheduling the appointment was excellent. Dan is doing a great job instructing Tim on hitting. Tim is very happy to have Dan as an instructor and we’ll be back again scheduling more appointments with Dan soon. Tim has been going to Maple Zone for several years and we are very happy with the services.

The instruction and guidance offered to Michael by Corey during a batting session is truly appreciated. Just to see Michael’s expression when he gets that “ha-ha” moment after Corey improves his swing or stance is priceless. Everyone at MSI is truly wonderful. Please convey my Thank you!

We couldn’t be happier, Rizz is a great instructor!

Tom Gartland, MSI Parent

Things are going great. Our 10 year old is really learning a lot. Matt is wonderful and my son really likes him. We’ve been to a few places before. This has been our best experience.

My son Ryan Beyer just completed his 8th pitching lesson with Todd Rizzo last Thursday, and I just wanted you to know how much Todd did to help Ryan improve. I was really impressed with how Coach Rizzo explained things to Ryan in an adult way, but a style that was easy for a kid to understand. He gave Ryan a lot of confidence and re-assurance as to his delivery mechanics and his abilities. I have to say that I was amazed and impressed by Coach Rizzos ability to spot even the smallest mechanical flaw and explain how it impacted his pitches in both location and velocity. Ryan has a pretty decent arm for a 10 year old kid, but last year, he really struggled with his control. He used to walk more than he struck out. This year, his first game at BYC, he threw 33 pitches, 28 of them were strikes, and he struck out the first 9 guys he faced. Needless to say, he was walking around on 3 feet of air after the game. I’ve never seen my son so happy and proud. So, I just wanted to let you know, since you are the general manager of MSI, that Todd did an outstanding job with my son. Cant say enough good things about the guy!! The lessons were super helpful and effective. Thanks
