You don’t need to train based on a 7 day week.
Convenience is often why 7 day splits are created.
For clarity, a 7 days spit is a training routine that repeats every 7 days.
A 5 day split would therefore not be training Monday to Friday with sat/sun off to start again Monday, that’s a 7 day split.
The aforementioned 5 day split would be perhaps train Monday/Tuesday/Recovery-Wed/Thursday/Friday-Off & repeat, so not adhering to the same training days each week.
Feeling the need to train on specific days each week can lead to some poor behaviours.
Skipping social events.
Binning off family to train.
Getting stressed when you miss a day.
Plus a whole host of other things as well, all of which lead you to stagnation, self loathing, little progress and eventual burnout.
Here are some different options to consider:
3 day splits – two days on, one off, repeat
Train every 3rd day after strength, 5th day after volume
Roll a dice to see how many sessions you do this week
Flip a coin to decide if you’re training or resting
Train 2 days one week, three the next, 4 after, then 2 again
Lift 3 times in 10 days, or 5 times in 14 days
The options are endless
Basically break the mould, especially if you say you like different things or variety.
Nothing is more different than rolling a dice to see if you’re training or flipping a coin.
Give the compulsive habit away willingly.
You’ll be amazed how your life improves and your stress levels reduce when you do,plus you’ll probably start getting better results as well due to not simply running through the motions in the gym.
You should investigate this thoroughly.
