Greetings @carlos84 ❤️💕
The aptitude of the trainer in this case is related to the trainer's ability to acquire and develop skills to be the best he/she can be in the training process.
This made me remember the concept and relationship between a mentor and a mentee. One of the major criteria in selecting a mentor is to ensure that the mentor is qualified and best in his/her field of specialization because the mentee follows the foot path of his/her mentor. The same applies to the trainer in this type of of scenario.
Thanks for sharing this great post with love from @hardaeborla and I hope you have a great day ahead ❤️💕❤️
