Does isometric exercise lower blood pressure? What wall sits and handgrips do

Isometric exercise lowered resting blood pressure by about 5 to 9 mmHg in pooled trials. Evidence is limited and some trials found no change.

Published October 2026

Short answer

Yes — pooled trials show handgrip and wall-sit training lowers resting blood pressure by roughly 5 to 9 mmHg, and a 270-trial review ranked it the top exercise type. Evidence is limited and no trial measured heart attacks or strokes. Evidence grade C (Limited). Many meta-analyses of randomised trials agree that resting blood pressure falls, but the evidence is downgraded twice: blood pressure is a surrogate marker, not heart attacks or strokes, and results are inconsistent (high heterogeneity, several null trials, ambulatory pressure mostly unchanged).

Key takeaways

  • In a review of 270 randomised trials with 15,827 people, isometric training lowered resting systolic blood pressure by 8.2 mmHg and diastolic by 4.0 mmHg on average — the largest drops of five exercise types [1].
  • Reviews of isometric training in people with high blood pressure found systolic reductions of about 5 to 8 mmHg [2][3][4][5].
  • Wall squats were the top isometric form in the largest analysis, and one session a week kept the benefit in a 24-week workplace trial [1][6].
  • The evidence is graded limited: several trials found no change, and 24-hour ambulatory readings improved in only a few studies [7][8].
  • Blood pressure rises during each hold, so people with uncontrolled blood pressure or a heart condition should ask a doctor first [9].

The short version

Isometric exercise is a form of strength training where you hold a muscle contraction without moving the joint, such as a handgrip squeeze or a wall sit [10][4]. Pooled trials show it lowers resting blood pressure [2]. In the largest review, it cut systolic pressure by 8.2 mmHg on average — more than aerobic, resistance or interval training [1]. Other reviews found drops of about 5 to 9 mmHg in people with high blood pressure [4][5]. The evidence is graded limited: trials are short, some found no change, and they measured blood pressure rather than heart attacks or strokes [2][8].

What the studies show

A 2023 network meta-analysis — a review that compares many treatments at once — pooled 270 randomised trials with 15,827 adults [1]. Isometric training lowered resting systolic blood pressure by 8.2 mmHg and diastolic by 4.0 mmHg, and it ranked first of five exercise types, ahead of combined training, dynamic resistance training, aerobic training and interval training [1]. Wall squats were the best isometric form in that analysis [1].

Reviews focused on isometric training agree on the direction: in people with hypertension, 12 trials with 415 people found average drops of 7.5 mmHg systolic and 3.2 mmHg diastolic, plus lower night-time pressure [2]. A 2026 review of 31 studies with 905 people found drops of 5.4 and 2.7 mmHg, larger in people with high blood pressure than in people with normal blood pressure [4]. A 2025 meta-analysis of 30 studies in people with prehypertension to established hypertension found drops of 7.3 mmHg systolic, 3.9 mmHg diastolic and 5.9 mmHg mean arterial pressure [5]. A 2026 review of 40 trials found 6.7 and 2.7 mmHg [11]. A 2023 review of 9 trials found handgrip training lowered systolic pressure by 6.7 mmHg and diastolic by 4.5 mmHg, while a single session had no effect [3].

Individual trials. In 77 adults with untreated high blood pressure, a 24-week workplace trial found systolic pressure fell 11.2 mmHg with handgrips and 12.9 mmHg with wall squats, against almost no change in controls [6]. A year-long trial in 24 men with high-normal pressure found drops of 8.5 and 7.3 mmHg with three wall-squat sessions a week, and 77% of sessions were completed [12]. In 54 people aged 60 and over, handgrips lowered office and 24-hour systolic pressure about as much as brisk walking or cycling over 12 weeks, and lowered diastolic pressure more [13]. In 84 older adults, office systolic pressure fell 8.0 mmHg with a home handgrip routine and 5.6 mmHg with walking, with no difference between groups [14]. Even light squeezes worked in one trial: 12 weeks at 15% of maximum strength lowered morning home systolic pressure by about 4 mmHg versus controls [15].

Who benefits most. Drops are larger in people who start with higher blood pressure [4][5]. In a review of handgrip trials, men and women of all ages benefited, with the largest average drop in older women (6.5 mmHg systolic) [16]. In young, healthy adults the falls were smaller — about 4 to 5 mmHg systolic, with no diastolic change [17].

The nuances

Not every trial agrees: a 12-week trial in 75 adults with hypertension found a five-session-a-week handgrip routine did not beat sham exercise, while aerobic exercise lowered 24-hour blood pressure [18]. Two 10-week trials in men already on blood pressure treatment found handgrip training did not lower pressure on its own [19][20]. A 20-week home handgrip trial in 48 adults was no better than usual care [7]. Many analyses also report wide variation between trials [4].

Ambulatory readings — a monitor you wear for 24 hours — improve less reliably: a review of handgrip trials found only awake diastolic pressure fell, by about 2 mmHg [8], and the hypertension review found night-time drops but no change in the 24-hour average [2]. One 12-week trial in older adults did find 24-hour systolic drops with handgrips [13].

Doses used in the trials: handgrips — four 2-minute holds at 30% of maximum strength, three times a week for at least 8 weeks [4]; wall squats — 4 x 2 minutes at roughly 85% to 95% of peak heart rate, three times a week [5]. Two sessions a week worked as well as four in one trial [17], and once-weekly sessions maintained the gains in the workplace trial [6].

Safety: blood pressure rises during each hold. In 26 men with stage 1 hypertension, systolic pressure averaged 173 mmHg during wall-squat training and some diastolic readings passed 115 mmHg; no adverse effects were reported, but the authors suggest individualising training when blood pressure is not well controlled [9]. Holds that use large muscle groups, such as deadlifts or two-leg extensions, push pressure higher than handgrips do [21]. If your blood pressure is uncontrolled or you have a heart condition, ask a doctor before starting [9]. The Isometric Exercise page has the full safety list.

What this means for you

The main practical appeal is time and equipment: the workplace routine took about 42 minutes a week at the start and about 12 minutes a week to keep the benefit, using only a wall [6]. Handgrip protocols were also described as low-cost [22]. For people with high blood pressure, the drops in office readings match those from walking or cycling in the trials that compared them [13][14]. Trials in people already taking blood-pressure medication tested isometric training alongside it, not instead of it [23][15]. A 390-person randomised trial is now testing wall squats against stretching, with 24-hour blood pressure as the main outcome [10].
