How about going straight to the truth for your strength and exercise? Straight to Hashem. Boruch hanosein layoeif coach
Blessed is Hashem for giving me strength. Your strength doesn’t come from your sleep or morning coffee and meals but comes directly from Hashem. Sure we all need to do our hishtadlus but everything comes directly from Hashem.
A person can sleep for 12 hours and still be more tired than someone else who slept only 6 hours. Cause your strength is not dependant on exercise and sleep and food etc… Bit comes directly from Hashem.
May Hashem help you and may you come to realize this very soon
