This is an awesome and quick workout you can do on your own. You can superset these exercises or use them on their own for a major tricep workout.
Marja Toan will be showcasing the more advanced technique of each exercise while Angie Palange will be showing the more modified versions for those just starting.
Here is their tricep workout:
Overhead Tricep Extension
Do anywhere between 3-5 sets of each, 10-15 reps each set. If you’re just starting out, try the modified techniques first and go with lighter weight and higher reps. Go for a set number of reps and sets, but when you feel that is too easy, begin doing each set to failure or increase the weight. For those more advanced, lift heavy! and go till failure. Push yourself!
