Never Give Up (In All Labor There is Profit- Proverbs 14:23)
I can't tell you how many times clients workout for 2, 3, 6+ months while making very slow progress ...then BOOM...everything seems to click for them and they start making really fast progress.
I've seen this too many times to know it's not a coincidence. If the goal is worth attaining, don't slow down. Keep pressing on. The work you're putting in IS worth it, even if it doesn't feel like it.
