Six ways to train with us. Each program runs through the same loop: assess, prescribe, measure, adjust. Pricing varies by program and is updated each year.
Private 1:1 or small-group sessions
Work one-on-one or with a friend in private sessions. Certified trainers build a custom routine around your goals, sport or non-sport. We've trained first-round NFL and MLB draft picks, athletes who represented the country in track and field, and individuals in their 90s. Show up ready to work.
Biomechanics, technique, and high-speed tech
Coaches teach proper biomechanics using high-speed video and tech. We've worked with thousands of players from age 6 to the major leagues, improving timing, direction, and sequencing. Players have added 30-40 mph in throwing speed and exit velocity. Numerous athletes hit 100+ mph exit velocity and 90+ mph fastballs.
Customized programs + full facility access
Athletes 14-21 get customized programs and professional coaching every visit. Access to 40 yards of turf and our weight room. Train like a pro without the per-session cost. Most of our All-Americans, sprint-record holders, and draft picks came through this program.
Assessment / approval required
Year-round programs for younger athletes
Year-round camps and clinics for ages 8-13. Baseball, softball, and summer performance options. Younger players build proper technique in a fun environment that grows confidence alongside skill.
Custom plans for athletes who can't train in person
Custom training plans for athletes who can't make it to the facility. Twenty years of remote work has helped produce NFL All-Pros, MLB players, and first-round draft picks in both sports. Limited to roughly 10 athletes at a time. Not a plug-and-play program.
Limited to 10 athletes per month
Reserve the space for teams and bulk training

Case · 01 of 12
On June 6, 2014, Isan Diaz became one of the highest-drafted high school position players ever to come out of Western Massachusetts. The Arizona Diamondbacks took him 70th overall in the second round. Diaz spent the off-season at Powerhouse before his 2014 high school season. He added close to ten pounds of muscle and pushed his bat speed from the mid-80s into the low-90s. His draft stock climbed from the 98th-ranked high school prospect to 55th, then to 70th overall (34th high school player taken).
