Most of the people I know who currently attend the traditional Latin Mass ("Tridentine" is not wholly accurate, but that is another discussion) do follow the traditional "lifestyle" including fasting from midnight before Sunday Mass (which is more of a challenge today because not every TLM is offered in the morning), Lenten fasting and abstinence, abstinence on Fridays, and devotions such as novenas, Benediction and Adoration.
See, I can totally relate to that! We are required to fast from midnight (and that includes abstinance from passionate activities as well) and confession before receiving communion. Confessions are usually given during the Hours precedind the DL by 45 minutes. Some parishes offer confession at vespers on satuday night, but confession just prior to the DL are favored.
Stict fast during the Great Lent is a given, and so is bi-weekly abstinance from meats and animal products on Wednesdays and Fridays.
