2) Lift heavy even when losing weight
Too many people make the mistake of switching from building muscle and lifting heavy to lifting 5 pound pink dumbbells for 50 reps once they start trying to lose weight.
DON’T DO THIS.
Maintaining your strength should be your #1 priority when trying to lose weight. What do you think happens when you switch from pushing 100 pound dumbbells to 10 pound lady weights? That’s right, you lose strength, lose muscle, and look like shit.
I’m not saying you need to max out on every set, but the weight needs to be challenging.
