Question 1

Why am I most sore two days after a workout?

Accepted Answer

That delay is the defining feature of **delayed onset muscle soreness (DOMS)**. It typically begins 12–24 hours after training, peaks around 24–72 hours, and fades within about five to seven days.

**It is not lactic acid.** This is one of the most persistent myths in fitness. Lactate is cleared from the blood within roughly an hour of finishing exercise — long before the soreness arrives. The timing alone rules it out.

What actually causes DOMS is **microscopic damage to muscle fibres and the connective tissue around them**, followed by an inflammatory repair response. The delay exists because the inflammation takes time to develop. Nerve endings become sensitised, which is why the muscle hurts when you press it or stretch it rather than aching constantly.

**Eccentric contractions cause it most** — the lengthening phase, where the muscle resists while extending. Lowering a weight slowly, running downhill, and the descent of a squat all produce far more DOMS than the lifting phase. This is why walking down stairs after leg day is worse than walking up.

**Soreness is not a measure of a good workout.** It mostly reflects novelty. A movement you have never done, or one you have not done in months, produces soreness regardless of how effective it was. Trained people get less sore doing the same session, and they are not getting less benefit. Chasing soreness as feedback leads to constantly changing programmes, which undermines progression.

**What helps:** light movement, which increases blood flow, generally helps more than complete rest. Sleep and adequate protein support repair.

**What to watch for:** severe pain, significant swelling, or dark cola-coloured urine after very intense unaccustomed exercise are not normal DOMS and warrant urgent medical attention.

Question 2

What happens when you start exercising after years off?

Accepted Answer

A predictable sequence of adaptations, most of which are invisible and fast, alongside a set of early experiences that make people quit before the benefits arrive. What changes, and when: Immediately

Question 3

What is the lactate threshold, and what is lactate actually doing?

Accepted Answer

The intensity above which lactate appears in the blood faster than it can be cleared, so it accumulates. It is one of the best predictors of endurance performance — and almost everything people

Question 4

Does stretching before exercise prevent injury?

Accepted Answer

The evidence does not support it, at least not for the kind of stretching most people do before training. Static stretching — holding a position for 30 seconds or more — has been studied extensively

Question 5

Why does the scale go up after a hard workout?

Accepted Answer

Almost always water, and it has nothing to do with fat. Several mechanisms push weight up temporarily after intense training: Glycogen and its water. Muscles store carbohydrate as glycogen, and each

Question 6

Do ice baths and cold water immersion actually help recovery?

Accepted Answer

They reliably reduce soreness and how you feel, and the evidence is much less flattering about whether they help you adapt — in fact, for strength and muscle growth, regular post-training cold

Question 7

How do tendons and ligaments adapt, and why are they slower than muscle?

Accepted Answer

They adapt through collagen remodelling, which is a fundamentally slower process than muscle protein turnover — and this mismatch is the single most common reason enthusiastic training produces
