This gets framed as a rivalry more often than it should. The real answer isn't "one is better" — it's that group classes and solo training solve two completely different problems, and most people have only ever diagnosed one of them.

The Case for Group Classes

Group training solves an adherence problem. The single biggest predictor of results in fitness isn't program design — it's whether you actually show up, week after week, for months. Group classes build in accountability structures that solo training doesn't: a scheduled time slot you're less likely to skip, a coach cueing you in real time, and — this part gets underrated — social pressure in the good sense. Research on exercise adherence consistently shows that people training in groups report higher session attendance than people training alone, largely because skipping a solo session only lets yourself down, while skipping a class means not showing up for a room of people who noticed.

Group formats like HIIT, boxing, or conditioning-style classes are also just efficient. A well-run 45-minute class can deliver a genuinely hard, well-programmed session without you having to think about exercise selection, rest periods, or what to do next. For people early in their training career, or anyone who finds programming overwhelming, that's a real advantage.

The Case for Solo (or 1-on-1) Training

Solo training solves a specificity problem. If you have a particular goal — rehabbing a shoulder, building toward a specific strength number, training around an injury history, or simply progressing at a rate that a group format can't accommodate — you need programming built around you, not around what works for a room of 15 people with different training ages and goals.

This is also where technical skill development tends to happen. Group classes, by necessity, can't give you the same coaching attention on your deadlift setup that a 1-on-1 session can. If your goal involves a technical lift, a specific sport, or working around a physical limitation, individualized coaching isn't a luxury — it's the actual mechanism by which you improve safely.

So Which One Should You Pick?

Ask yourself honestly which of these is your actual bottleneck:

  • "I know what to do, I just don't do it consistently" → Group classes. Solve the adherence problem first; everything else is downstream of showing up.
  • "I show up every time but I'm not progressing, or I'm training around a limitation" → 1-on-1 coaching. You need specificity, not more accountability.
  • "I want both" → A lot of our members do exactly this — group classes for volume and community, one coaching session every couple of weeks to check in on technique and adjust the plan.

There's no prize for picking the "harder" or more "serious" option. The right format is whichever one you'll actually keep doing.
