EZ Barbell Lying Triceps Extension: Do your elbows flare out?
Keep your elbows shoulder-width apart as you slowly lower the bar toward your head, then press it up until your arms are fully straight. Do not let your elbows flare out.
How to fix it
- Lie on your back on a bench with both feet flat on the floor.
- Keep your elbows shoulder-width apart as you slowly lower the bar toward your head.
- From the lowered position, press the bar up until your arms are fully straight.
The app sets the reps for your next set
(For exercises you added to your routine yourself) For example, if you are a beginner and completed all 14 reps in each set at 20kg as planned in your last workout, the app keeps the weight the same and increases your reps to 15. When you log your sets, GYMKC reads your last set and recalculates the weight and reps for your next set.

Sources differ slightly. Some suggest lowering it to your forehead or the top of your head. Others suggest lowering it behind your head. Either way, lower the bar slowly and with control.
