How can I effectively target my triceps using a French press technique with dumbbells?

To effectively target your triceps using a French press technique with dumbbells, lie on a bench with a dumbbell in each hand. Extend your arms straight up, then bend at the elbows to lower the dumbbells towards your forehead. Keep your elbows close to your head and extend your arms back up to complete the rep. This exercise isolates and strengthens the triceps muscles.
