Congratulations to @JThompson_2026 on his commitment to continue his academic and athletic career at @QUHawksBaseball . We are proud and excited for you Jeremy!

[Missy Mitchell-McBeth @missyMmcbeth]

Training is often monotonous. It’s not always novel and exciting. Neither is a sport practice. Neither is life.

Lock in anyway.

[Pete Collopy MS RSCC @CollopyPete]

HS Strength & Conditioning simply defined - you get out what you put in.

Don’t show up - no improvement

Show up and go through the motions - some improvement

Show up and put in work consistently for years - you’ll unlock physical capabilities you never thought you’d have

[Spartans Baseball @rhsspartansbb]

Great player and better person.

@JThompson_2026 is a leader in and off the field.

3.8+ GPA and will outwork anyone on the field.

Get him on your roster!

Spartans move to 4-3! Richard Conley breaks career passing record and Caleb Patterson breaks single season interception record!

[Gerry DeFilippo @Challenger_ST]

Average young athlete: “I need to do new exercises & programs every week.”

What the average young athlete actually needs to do 52 weeks per year:

1. Sprint
2. Jump
3. Lift heavy
4. Do it all in multiple planes
5. Progressively load & ramp intensity

Wash, rinse, repeat.

Work in the classroom is just as important as work in the field💯 #StudentAthlete @RhsSpartanfball

[Romeoville Spartan Football @RhsSpartanfball]

3-0!!!!

[Fred Duncan @Fred__Duncan]

Outside of every coach’s favorite “odd” exercise here and there, the bulk of your work as an athlete should look pretty simple…sprinting, jumping, choosing an explosive movement (med ball, Olympic variation, plyo), and getting stronger in a few core lifts.

That combination.

[Romeoville Spartan Football @RhsSpartanfball]

2-0!!! Big win on senior night!

Speed testing from last week. This year we are using the 20-30yd Fly and 5-15yd Fly as our KPIs for top end speed and acceleration. #SpartanSpeed

Are you a Serious Lifter or a Pretender?

Serious:
✅ Form technician in training
✅ Knows rest = growth
✅ Listens to their body
✅ Patience + constant progress

Pretender:
❌ Too heavy, too often
❌ Maxes out every set
❌ Ego drives decisions
❌ Needs instant gratification
