Learn Turkish: Omurganızı gevşetmekte ne kadar zorlanıyorsunuz? - How much are you struggling to relax your spine?

The verb zorlanmak (to struggle / to have difficulty) specifically governs the locative case when referring to an action. In Turkish, you struggle 'in' doing something. To express this, we take the infinitive gevşetmek and add the locative suffix -te, creating the -mAktA zorlanmak pattern.

Does the -mekte in gevşetmekte have anything to do with the continuous tense?

Not in this sentence! While -mAktA is sometimes used as a formal equivalent to the present continuous -Iyor (like yapmaktayım for 'I am doing'), here it is simply the infinitive -mEk plus the locative case -tE. It functions entirely as a noun phrase ('in relaxing') to pair with the main verb zorlanıyorsunuz.

I know gevşemek means 'to relax.' Why is there a -t- in gevşetmekte?

Gevşemek is intransitive, meaning 'to become relaxed' or 'to loosen up' (e.g., your body relaxes on its own). However, here you are taking action to relax a specific object (your spine). The -t- is a causative suffix that turns the verb into a transitive one: gevşetmek (to relax something / to make something loose).
