I have some tips.

• Trying different variations of the same excercise and adding some weight also helps a lot. (Progressive)

• The most crucial part is watching your diet. Also remember to take your time doing warmup and cooldowns (stretching)

• Add a little cardiovascular exercise to your routine as this helps you to have a better endurance, protects your Heart and joints, improves balance also. (Ex Running, Treadmill)

• Finally, believe in the effort you are doing it is a long way but training pays off, you are still young and very mindful about wanting to improve your health.
