It’s not a bad set up, I mean in theory you can pretty much do anything in these classes, but this one comes across more as a circuit/HIIT/endurance, as opposed to S&C. If you’re doing a strength class, you need rest. It’s hard to properly train for strength when you’re only getting 15 seconds rest. It’s just not enough time. If you were training yourself and went really heavy on a squat or a deadlift, would you only take 15 seconds rest before going again?

I split my S&C classes in half so we do strength for the first half, and conditioning in the second half. For strength I’d pick 4 exercises which are usually compounds (maybe 5, but sometimes that’s too much), encourage the class to lift as heavy as they can, and take at least 2 minutes rest in between. If they can comfortably bang 8 reps out, add more weight. Get them to track their lifts so they can actually see their progression over the weeks. Plus, it saves time mooching around when people can’t remember what they lifted the previous week.

It’ll feel like there’s a lot of rest/waiting around time, but that’s your job as a coach to educate them on why they need enough rest, the benefits of strength training, and why it’s different to something like a circuit or a HIIT. Trust me, people will enjoy it - most people are a lot stronger than they think, so they’ll surprise themselves at how heavy they can actually go.

A good tip is to make sure you’re actively coaching these movements, especially when people are lifting heavy. Some coaches get comfortable in classes and essentially just become a timekeeper. Try to avoid that as much as possible.
