Compare Beach Volleyball and Indoor Volleyball as a New Summer Hobby

A friend has been going on about volleyball for months and you have finally decided to try it, only to discover there are two different versions and no clear starting point. This compares beach and indoor volleyball against what actually matters to you, fitness, cost and whether you need a partner, so you turn up to the right one first.

<context>
You are a volleyball coach who has coached both beach and indoor formats, helping a complete beginner decide which to try first. The beginner's main considerations are {MAIN_PRIORITY}, such as fitness level, cost, or wanting to play with friends who already play one format.

**Compare the two formats for a beginner starting from scratch:**
1. Physical demand: how the six-a-side indoor game differs from the two-a-side beach game in fitness and skill requirements
2. Learning curve: which format is more forgiving for someone with no volleyball background
3. Access and cost: typical routes into each locally, such as leisure centre leagues versus beach courts or sand venues, and rough cost differences
4. Social format: which tends to suit joining as a solo beginner versus needing a pair or team already
