Blood pressure for lifters: numbers, checks and training

UK and US blood pressure thresholds, how to take a reliable home reading, and why lifting raises blood pressure briefly but tends to lower it over time.

For lifters it is worth understanding two separate things: the big, short spike during a heavy set, and your resting blood pressure, which is what matters for long-term heart and blood vessel health. This guide covers the thresholds, how to measure properly at home, and what pushes the numbers up or down.

What the numbers mean

A reading has two numbers in mmHg: systolic (the pressure when your heart beats) over diastolic (the pressure between beats). UK and US guidelines draw the lines in different places, so the same reading can be labelled differently depending on where you live.

UK (NICE and NHS)

The NHS treats 140/90 or higher at a clinic, or 135/85 or higher at home, as high blood pressure ^[2]. NICE uses these stages ^[1]:

US (AHA/ACC)

The American Heart Association uses lower cut-offs ^[4]:

The 2025 AHA/ACC guideline kept the 130/80 and 140/90 cut-offs ^[5]. In short: a reading of 132/84 is stage 1 hypertension in the US but below the UK threshold. Your doctor will use the local guideline and your overall risk.

How to measure at home properly

One reading tells you little. A routine is far more useful.

• Use a monitor with an upper-arm cuff rather than a wrist monitor, and make sure the cuff is the right size for your arm ^[10]. Lifters with big arms may need a larger cuff.
• Sit on an upright chair with your back supported and feet flat on the floor ^[3].
• Rest your arm on a table, relaxed, with the cuff on bare skin rather than over a sleeve ^[3].
• Sit quietly first, breathe normally and do not talk during the reading ^[3].
• Take a second reading a minute or so later to check the first ^{[1, 3]}.
• Do not measure straight after training, caffeine or a cigarette. These are practical points, not thresholds: you want your true resting number.

To get a proper average, NICE recommends two readings at least one minute apart, seated, twice a day (ideally morning and evening) for at least 4 days and ideally 7. Discard the first day and average the rest ^[1]. The AHA/ACC also advises against relying on smartwatches or cuffless devices for blood pressure until they prove more accurate ^[5].

Lifting: the short spike vs the long-term effect

During a heavy set

Blood pressure rises sharply during heavy lifting, especially when you brace and hold your breath. In a classic study using a catheter in the artery, experienced bodybuilders doing a heavy double-leg press averaged a peak of 320/250 mmHg, and one exceeded 480/350 ^[6]. It lasts seconds and drops once the set ends. It is a normal response, not a sign that you have high blood pressure. If you have known heart disease or very high resting blood pressure, ask your doctor how hard you should push and whether to avoid long breath-holds.

Over weeks and months

The long-term picture is good. A 2023 meta-analysis of 270 randomised trials (15,827 people) found that dynamic resistance training lowered resting blood pressure by about 4.6/3.0 mmHg. Aerobic training lowered it by about 4.5/2.5, combined training by about 6.0/2.5 and isometric exercise (such as wall squats) by about 8.2/4.0 ^[7]. Mixing lifting with some cardio is a sensible default. See cardio and lifting.

What raises resting blood pressure

• Weight gain. Being overweight raises blood pressure, and reaching a healthy weight is a core recommendation ^{[2, 5]}. This matters if you bulk hard. See cutting and bulking.
• Alcohol. Drinking too much raises it, and guidelines advise cutting down or stopping ^{[1, 2, 5]}.
• Salt. A high-salt diet raises it, and lower sodium is advised ^{[1, 2, 5]}.
• Caffeine and stress. Heavy caffeine intake and long-term stress are listed as contributors ^{[1, 2]}.
• Some medicines and substances. The AHA lists decongestants, anti-inflammatory painkillers such as ibuprofen and naproxen, systemic corticosteroids, some antidepressants, birth control pills, stimulant drugs and supplements such as ephedra ^[8]. Check with a pharmacist before taking cold remedies or painkillers regularly.
• Testosterone. In 2025 the US FDA required all testosterone products to carry information or a warning about increased blood pressure, based on 24-hour monitoring studies ^[9]. If you are on testosterone, check your blood pressure regularly and discuss any rise with your prescriber.

When to see a doctor

• If your home average is at or above the threshold for where you live, book a routine appointment. Bring your log.
• If a reading is above 180/120, wait a minute and measure again. If it is still that high and you have chest pain, shortness of breath, back pain, numbness, weakness, vision changes or difficulty speaking, call emergency services. If you have no symptoms, contact your doctor promptly ^[4].
• Call 999 (or your local emergency number) for sudden chest pain that spreads to your arm, neck or jaw, or comes with sweating, nausea, light-headedness or breathlessness ^[2].
• Contact NHS 111 or your GP if you often get headaches, blurred vision or chest pain that comes and goes ^[2].

Tracking it in ETS

If your cuff syncs to Health Connect, ETS can show your blood pressure readings alongside training, body weight and resting heart rate, so you can see whether a bulk or a change in routine lines up with a rise. Weigh-ins with a trend line help you spot slow weight gain early. Logged medications sit in the same place to show your doctor.
