Why strength matters

When you lose weight, you can lose some muscle as well as fat. Strength training, together with enough protein, helps you keep muscle — which supports strength, balance and everyday function.

What the guidelines say

UK guidelines recommend that adults do activities that strengthen all the major muscle groups — legs, hips, back, abdomen, chest, shoulders and arms — on at least two days a week, alongside at least 150 minutes of moderate activity.

Getting started

Start with a level that feels manageable and build up gradually.

Staying safe

If you have a health condition, an injury or haven’t been active for a while, check with a healthcare professional first. Stop if you feel pain, dizziness or chest discomfort.
