To mr. tayo Thank you for your correction and explanation! Your explanation is very helpful.

Recently, I've been taking a nap for about 2 hours after work. I don't know why I have been so sleepy lately. (adding the word "lately" here provides a contrast to a time before when the listener will assume you had more energy) I study English and lift weights so I want to have more time to dedicate to these activities. or - I study English and lift weights so I want more free time to dedicate to these activities. Couple of notes: In your first sentence you can start the sentence with the frequency word (最近、毎日、etc.). In Japanese you often do the same and its also more natural in English. 例えば。。。最近、仕事の後2時間ぐらい昼寝している。However, we also use those frequency words in the middle and end of sentences as well so just giving you an option here. Muscle training is a direct translation of 筋トレ . However, it's very unnatural (不自然）in English to say it this way. You would want to say "weight lifting" as Julie has stated. Also rather than stating "more time for free" its more natural to state "free time." So you would say "I want more free time to do __A_, __B__, and __C__." 英語の勉強は頑張って！
