Simple - try a combination of the above five moves - that's an Arnold press, seated overhead press, front raise, reverse flys, and lateral raises - and aim for three rounds of the movements. Each round, try 12 reps per movement.
To improve your strength, gradually increasing the weights you're lifting week on week is key. This is called progressive overload and will boost your shoulder strength over time rather than simply maintaining your current fitness levels.
If you don't have access to weights at home, using your body weight can be effective if done with correct form.
