If young women who are new to weightlifting eat enough calories (35–45 per kg of body weight), they get stronger from training—but if they eat too few (15–20 kcal/kg), they might actually lose strength even while training hard.

For women just starting weight training, how much they lift (total volume) matters a lot—but only if they also eat enough protein and calories. It’s the combo that makes a difference.

Lifting weights more often helps you get stronger, but after a certain point, you don’t get much stronger no matter how much more you lift—plus, this slowdown happens sooner for strength than for muscle growth.

Lifting more weights each week makes you stronger, but the extra strength you gain from each additional set gets smaller faster than the muscle gains do.

If you're a young guy lifting weights more often each week, you'll build more muscle and get stronger—but after a while, your strength stops improving fast, while your muscles keep growing a bit longer.

Doing more sets in your weight workouts might actually make you gain less muscle—each extra set could slightly reduce your muscle growth, so more isn’t always better.
