Events Don’t Upset You. Beliefs Do.
The Stoics are saying there are no good or bad events, there’s only perception.
You get dumped by someone you’re totally in love with. Feel sad? God, yes. The world is going to end.
Okay, same scenario, but afterwards you find out that person was actually a psychopath who killed their last three partners. Feel sad you got dumped? No, you’re thrilled.
So clearly “getting dumped” isn’t the important factor here. What changed? Nothing but your beliefs.

If you are riding an emotional rollercoaster of highs and lows and your outlook changes from hour to hour it is extremely difficult to establish a routine and stick to it long enough to experience the benefits (weight loss, increased energy, increased strength, better sleeping patterns).
Do we exercise to relieve stress and help us feel happier, yes? Can feeling happier benefit our exercise and weight loss? Absolutely! Training yourself mentally is every bit as important as training yourself physically.
Remember life is 1% what happens to you and 99% how you react to it.
