A brief, 10-minute sequence of floor exercises performed on the back appears to sharpen balance, lateral agility and trunk flexibility — and could offer a low-risk way to boost everyday movement, according to a new Japanese study. The research, published in April in PLOS One, suggests small, daily sessions that emphasize coordination rather than heavy loading can change how the body controls movement.
What researchers did
Teams from institutions including the Tokyo University of Agriculture and Technology tested a short program designed to connect the core with lower-limb actions while participants lay supine. The paper reports two separate experiments: one compared 17 healthy young men who completed the routine against a control period, and a second examined movement changes in 22 young adults using an agility task before and after two weeks of daily practice.

Balance and agility: ten-minute floor routine boosts both, new research shows
The routine focused on three components: controlled abdominal engagement, a bridge-style movement linking the torso and hips, and drills for the feet and ankles to refine coordination. Exercises were deliberately low-load and performed face-up, a posture the authors described as more stable than standing work.
Key findings
- Improved balance: Participants showed better standing balance after the two-week program.
- Better lateral agility: Side-to-side stepping and quick directional changes improved in the agility test.
- Greater trunk flexibility: Measures of spinal and hip mobility increased.
- No clear gains were seen in raw power or maximal strength measures such as grip strength, long jump distance or short sprint times.
Why this matters now
As fitness interest shifts toward practical movement quality and fall prevention, a simple, equipment-free routine that can be done on the floor may be attractive for morning warm-ups, rehabilitation plans or for people who avoid standing exercises because of balance concerns. The authors argue the gains reflect improved motor control and coordination — the nervous system learning to link the trunk and lower limbs more effectively — rather than muscle growth.
Expert perspective and limits
Outside experts caution the results are preliminary. One commentator noted that two weeks is too brief to expect significant muscle hypertrophy, so the reported improvements likely reflect neural adaptation and growing familiarity with the tests. Short-term practice effects can inflate early gains, especially in young, healthy participants.
The study has additional limitations that temper broad conclusions:
- Small sample sizes and short duration (two weeks).
- The second experiment lacked a formal control group.
- Participants were predominantly healthy young adults, limiting applicability to older or clinical populations.
- It remains unknown whether the measured changes translate into fewer falls or long-term functional benefits.
Practical takeaway
For people without injuries, a daily 10-minute supine routine that targets core stability and foot-ankle coordination may be a useful adjunct to a broader fitness plan — especially as a low-risk way to “wake up” balance and coordination systems. Because the approach is low-load and performed lying down, it removes immediate fall risk and requires no equipment.
Medical or rehabilitation professionals should be consulted before trying the sequence if you have existing balance problems, recent injuries, or other health concerns. The authors and independent experts both suggest the method merits further research in older adults and clinical groups to test whether short-term coordination gains can produce meaningful, lasting benefits.
