Ahman Green and Dr. Dave, FDL Rugby Tourney 

Dr. Dave gets to reunite with Ahman Green.  

Back in 2003, Dr. Dave was able to work with some Packers, one of which was Ahman.  Now, Ahman is playing rugby for the Green Bay Strikers and has hopes of making the USA Eagles 7 man program in time for the upcoming Olympics, when rugby makes a return.   Dr. Boll and Ahman came back together at a rugby tournament in Fond du Lac, where Dr. Dave's Sheboygan Sharks took 8th place, a few spots behind Ahman's Strikers.

Apex Athletic Performance is working out of the former Batavia Elementary School Building, W7140 School Drive, in Batavia. 


The former school allows us ample room to continue with our athletic performance training and camps.   The gym allows us to continue with speed, agility, acceleration and conditioning sessions/camps.  We have dedicated rooms for Olympic style athletic weight training and for functional training (Ropes, TRX, Plyo work, Kettlebells, etc).  The long hallways allows us to coach sprint training and do sled drags. 


Plus, we have 8 acres of land to have all sessions and camps outdoors too when the weather cooperates. 


We are very excited to have access to this great building that really suits our needs and allows us to expand our services. 

Apex Athletic Performance is proud to be associated with the Sheboygan Silverbacks Rugby Club!  We'll assist them with their training and conditioning needs, along with working with Sheboygan County Youth Rugby to set up an Academy Program.

What the athlete can expect during the camp:

  • Detailed functional movement prep warm up
  • Movement specific drills
  • Visual and objective evaluation
  • Coaching on conditioning and rehabilitation needs

The athlete should bring plenty of water, weather appropriate work out clothes in the event we can hold
some or all drills outside, a change of clothes (if possible) and running shoes. Optional, but helpful items that also can be brought along would be their mouthguard and cleats if the athlete uses those items for their sport in addition to normal running/training shoes.
