- After each set immediately followed with seated side db lateral raises

Dropsets:
- 4 sets seated db shoulder press (8-12 reps)
- Each set, immediately drop the weight by 20 pounds each db and press until you can't lift anymore
- For an added bonus, on the last drop set, do multiple drop sets instead of just 1.
The dropsets would be what I'd recommend the most as you're still doing a compound lift while trying to burn your muscles completely. However, if your triceps fail too early compared to your shoulders, the supersets might work better.
