The Old Boys finished third in the curtailed 2019-20 season behind Withycombe and city rivals Tamar Saracens.
But after 18 months without any competitive action due to the Covid-19 pandemic, the Elburton-based club know returning to a 14-strong Devon One in September will not be easy.
To help them prepare for the 2021-22 campaign, the Old Boys will be holding weekly fitness sessions over the summer.
They have joined forces with Zone Fitness at the Christian Mills Business Park, who are allowing the club to use their brand new facility to provide specialist strength and conditioning.
Fitness coach and first team winger Martin Skelly, a PE teacher, will lead the sessions on Tuesday evenings.
“We feel that this will be a major step forward for the club in our quest for improvement,” said head coach Rick Orkney.
“If we are going to challenge the top sides in the league next season we will need to be fitter than we currently are and this is the perfect opportunity in which to do so.
“Owner of Zone Fitness, John Williams, plays for the club when he can and has been instrumental in establishing this partnership.
“Part of the deal is to also allow senior members to have membership of the gym throughout the week so that players can train at times which suit them.
“We consider this to be a great perk of becoming a member of OPMs and is a statement that we are moving forward as a progressive and forward-thinking club.”
OPMs will kick-off their 2021-22 will a home game against city rivals Old Techs at King George V Playing Fields on September 4.
They will then visit Plymouth Argaum before hosting newcomers Salcombe, who have come up, and then heading to South Molton, who have come down from the Cornwall/Devon League.
