Declan Hallwood
Nutrition & Supplements Editor, Best Exercise
Protein, creatine, pre-workout and everyday supplements
Declan Hallwood has spent the better part of a decade writing about sports nutrition and training alongside it. He has worked his way through more protein powders, pre-workouts and recovery products than he can count, which makes him hard to impress and quick to spot marketing dressed up as science.
At Best Exercise he leads nutrition coverage, from protein and creatine to electrolytes and bars. He digs into ingredient lists, doses and the evidence behind the claims, and he is careful to separate what is genuinely useful from what is an expensive placebo. Any health claim is backed by a reputable source.
Declan's view is that most people need far fewer supplements than the industry would like them to buy. His job is to point you to the few that earn their place.

How we research and review
Researched, not guessed
Every recommendation is built from owner reviews, manufacturer specs and independent expert testing, cross-checked across the market.
Honest about trade-offs
We list the downsides as plainly as the strengths. A review that can't say what's wrong with a product isn't a review.
Independent rankings
We're funded by affiliate commissions but never led by them. No product earns a better place for paying more.
Kept up to date
Fitness kit changes. We revisit guides as models are revised, discontinued or replaced, and date every update.
