−8 mmHgaverage resting systolic drop, isometric exercise (wall squat performed best in secondary analysis)
Isometric exercise, especially the wall squat, shows the largest average drop in resting systolic blood pressure in a large network meta-analysis. Aerobic and combined training remain the guideline standard, though, and they have more consistent evidence, including for 24-hour blood pressure.
The isometric evidence rests on far fewer trials than the aerobic evidence does, so calling it a clear winner overstates what the data support.

Rest
Core sessions are 4 holds of 2 minutes each, with 1 to 4 minutes of rest in between. Swap in isometric handgrip if the wall squat is not practical. The optional aerobic sessions are skippable, since the core effect does not depend on them. Measure blood pressure before week 1, then again after 6 to 8 weeks.

Ranking for systolic pressure, by SUCRA score: isometric 98.3%, combined 75.7%, dynamic resistance 46.1%, aerobic 40.5%, HIIT 39.4%. In a secondary analysis, the isometric wall squat ranked best for systolic pressure, and running ranked best for diastolic pressure.
Subgroup estimates for systolic pressure
From the Examine summary of the same meta-analysis, estimates by specific exercise: walking −3, sprint interval training −5, cycling −7, running −7, handgrip −7, leg extension −10 mmHg. The wall squat figure was not visible in the source material, so no number for it is given here.
Running and cycling are tied at −7 mmHg, so neither should be called better than the other.
Walking shows a clearly smaller effect than the other modes listed.
The −10 mmHg figure belongs to the leg extension subgroup specifically, not to isometric exercise as a whole.
Other isometric meta-analyses
Edwards 2022, J Hypertens
18 studies, 628 participants. −9.35 mmHg systolic, −4.30 mmHg diastolic. The wall squat appeared most effective, but the authors note direct comparisons between isometric exercises are still needed.
Baffour-Awuah 2023, Curr Hypertens Rep
12 studies, 415 participants, hypertensive adults only. −7.47 mmHg systolic, −3.17 mmHg diastolic. No significant reduction in 24-hour or daytime ambulatory blood pressure.
Single RCT
77 unmedicated hypertensive adults. Systolic reduction of −11.2 mmHg (handgrip) and −12.9 mmHg (wall squat), versus −0.4 mmHg in controls. This is one trial, so the result should not be generalized.
24-hour ambulatory pressure (BJSM 2025)
31 RCTs, more than 1,345 participants, adults with hypertension (doi:10.1136/bjsports-2025-111474). Systolic reduction over 24 hours versus no exercise: combined −6.18, HIIT −5.71, aerobic −4.73 mmHg. Aerobic training was the most consistent mode for both day and night readings, while the evidence for isometric exercise alone was more limited.
Other context
A consensus analysis of 34 meta-analyses (Eur J Prev Cardiol, 2021) found aerobic exercise most effective for people with hypertension.
Guidelines still center on aerobic and dynamic resistance exercise. Isometrics are treated as an emerging add-on, not a replacement.
How long do the effects last?
Every reduction above is a chronic training effect: it builds up over weeks of repeated sessions and is measured at rest, not during exercise. A separate, much shorter effect happens within a single session: blood pressure rises during the contraction itself, then drops below baseline for a few minutes afterward, back to normal within about 10 minutes. These are not the same thing, though they may be connected, since people with a larger immediate post-exercise drop tend to show larger resting blood pressure drops after weeks of training.
Whether the chronic benefit survives once training stops is a separate, less-studied question, and the answer looks different depending on the mode.
Isometric leg training, with detraining
25 young, normotensive adults. 4 × 2-minute contractions at 20% MVC, 3 times a week for 8 weeks, using leg extension rather than handgrip. Resting systolic pressure: 123 mmHg at baseline, 117 after training, 119 after a further 8 weeks with no training at all. 24-hour ambulatory systolic pressure followed the same pattern: 123, then 115, then 117. Most of the benefit was still present after 8 weeks of detraining.
Aerobic, resistance and combined training, with detraining
A 6-month intervention mixing aerobic, resistance and combined training. Among participants who responded to training (systolic pressure down 11.5 mmHg on average), just 2 weeks of detraining reversed a large share of that benefit, and some participants' pressure rose back above where it started.
No detraining study has tested handgrip specifically. The durability evidence above comes from isometric leg-extension training in healthy young adults with normal blood pressure, not from handgrip in hypertensive adults.
On the evidence that exists, isometric training looks like it holds its benefit longer after stopping than aerobic or resistance training does, but this is an indirect comparison across different studies and populations, not a head-to-head test.
Caveats
The comparison between modes is indirect, since it comes from a network meta-analysis, so the rankings should be read with caution.
The isometric evidence base is thin: 24 trials, compared with 182 for aerobic exercise.
The confidence intervals for isometric and combined training overlap substantially, so the gap between them is not as clear-cut as the point estimates suggest.
Isometric holds raise blood pressure temporarily during the effort itself, even though resting pressure drops afterward.
Aerobic vs. anaerobic, briefly
Aerobic means "with oxygen": longer, lower-intensity effort such as jogging or cycling, where the body keeps up with oxygen demand.
Anaerobic means "without oxygen": short, intense bursts such as sprinting, heavy lifting and HIIT, which produce lactate as a byproduct.
This is a spectrum rather than two separate buckets, because the body never relies on only one energy system. A systematic review of maximal exercise estimated that the two systems contribute roughly equally at around 78.6 seconds of effort.
Suggested routine
A time-efficient approach built around the strongest single finding, with aerobic work kept as a secondary layer rather than dropped.
Core: isometric wall squats, about 15 minutes, 3 times a week
4 holds of 2 minutes each, with 1 to 4 minutes of rest between holds.
Breathe normally during each hold, rather than holding your breath.
Expected effect: about −8 mmHg systolic on average, based on Edwards 2023.
Optional top-up: 1 to 2 short aerobic sessions a week
Running or cycling over easy walking, since walking showed a clearly smaller effect.
HIIT is the time-efficient aerobic option if sessions need to stay short.
Aerobic training also produced the most consistent 24-hour blood pressure readings.
Fallback: isometric handgrip
The best-studied isometric mode overall, though probably a smaller effect than the wall squat.
Monitoring
Measure blood pressure before starting, then again after 6 to 8 weeks, to see whether it is actually moving.
