Q: When should I use E45 instead of E30?

Use E45 when your movement has more setup — cleans, press complexes, or heavy swings that need a reset. E30 is tight for anything but pure ballistics.

Every 45 seconds on the 45. The extra 15 seconds over E30 gives more room for complex movements, cleans, short press complexes, or any movement that needs a reset between reps. This timer fires an audio cue every 45 seconds; configure 10 to 20 rounds before you start.

Configure the number of rounds (10–20) before starting. The timer fires a start beep and the first 45-second window begins immediately.

Complete your reps within the window, then rest until the next beep. With 45 seconds you can comfortably do 5–8 reps of most movements and still have meaningful rest.

The extra 15 seconds over E30 makes this the right format for cleans, push presses, and any movement where setup time matters. A completion tone fires after the final round.

When should I use E45 instead of E30?

Use E45 when your movement has more setup — cleans and re-grips, press complexes, or heavy swings that need a back-swing reset. E30 is tight for anything but pure ballistics. E45 gives room to move well and still rest meaningfully before the next window.

How many reps per 45-second window?

5–8 reps for most movements. For complexes (e.g., clean + press), 3–5 reps per side. You should finish with at least 10–15 seconds of rest. If you're rushing to beat the beep, reduce reps or weight.

What weight should I use?

Similar to your E30 working weight or slightly heavier since the extra time allows for heavier loads. For single-arm work, most men use 24–32 kg. For complexes, load to your press maximum.

Does the timer work offline?

Yes. Iron Timer is a PWA. After the first load it works without internet and the screen stays on throughout your session.

Can I use E45 for double-bell work?

Yes. The 45-second window is particularly useful for double-KB movements like double cleans or double presses where you need time to set the grip and position properly.
