A Parent’s Guide to Feeding Strong Athletes

We’re full-time working parents raising three busy athletes. Between practices, games, and school schedules, we know what it’s like to be constantly on the go and scrambling for dinner ideas, snacks to pack, or what to grab from the drive-thru.

That’s why we started creating simple cheat sheets for our own kids — to make fueling easier, faster, and less stressful. And now we’re sharing them with other families who are in the same boat.

Ed Mantie

Ed is a former Division I athlete who began his career as a strength coach at Mike Boyle Strength and Conditioning before moving on to serve as the Head Strength and Conditioning Coach for UMass Lowell hockey. He later transitioned into teaching and coaching, spending the past 18 years as a physical education and wellness teacher, as well as a head football coach at Weston, Framingham, and Boston College High School.

Ed also coached at the collegiate level at Curry College before stepping away from football to focus on growing Mantie Strength Academy with Keri. This shift has allowed him to bring together his experience as an athlete, teacher, and coach — while also being on the sidelines to watch his three sons play the sports they love.
