Separate applying from attempting selection
The British Army's SAS Reserve role page says applicants without previous military service can begin a route to joining. It also says they must complete basic military and trade training and gain experience before being allowed to attempt selection. A private coach who presents direct civilian entry to a selection course is leaving out a critical prerequisite.
Follow the Army's actual process
The official page directs applicants towards recruitment channels and Army Reserve training. The sequence, age eligibility and entry circumstances are decided there, not by a preparation website. Requirements can change, so compare the current official description with the instructions provided to you personally.
Allow for the time you do not control
People sometimes imagine an exact selection date before they have established military eligibility. An honest preparation plan should instead show known decisions, approximate personal goals and the steps that only the Army can authorise. Treat Reserve obligations, work and family commitments as real inputs rather than minor inconveniences.
Understand what civilian fitness preparation can and cannot do
General aerobic capacity, strength, recovery habits and outdoor safety skills may be useful foundations. They are not equivalent to initial Army training, do not entitle you to selection and cannot substitute for the directions of serving training staff. A coach should be transparent about where their competence stops.
Do not mistake a web enquiry for recruitment
This independent publication has no authority to process military applications or verify an individual's eligibility. Use Army channels for those matters. Avoid sending service records, health documents or identity information through an independent site.
A practical decision exercise
Draw a line between 'I can do this independently' and 'the Army must authorise this'. Put public fitness learning on the first side; eligibility and selection dates on the second.
