Hello! Neither, but you should pay attention to a sensible training right now with 14. It must not be one-sided, as far as possible all major muscle groups should be addressed :

• Arm muscle.
• Leg muscle.
• Back muscle.
• Breast muscle.
• abdominal muscle.
• Shoulder muscle.

And watch a clean technique on the knee bows, otherwise they are dangerous

Great success, beautiful week
