The Lululemon Energy Bra is the brand’s answer for women who hate buying sports bras in vague S, M, L sizing and want their cup-and-band fit to actually mean something. Six months into wearing mine, the cup-specific fit has held up across 35-plus wash cycles, the strappy back has not loosened, and the removable pads still sit flat without bunching. It is not a high-support bra. For yoga, pilates, walking, and moderate cardio, however, the Energy is one of the most reliable medium-impact options at this price.
Why you should trust this review
I have been writing about activewear since 2019 and have tested cup-sized sports bras across nine brands. For this review I purchased one Energy Bra at retail in Black, size 34DD. Lululemon did not provide a sample. The bra went through approximately 35 wash cycles on cold, line-dried indoors. I tracked fit accuracy, support during medium-impact activity, pad performance, and elastic recovery at month 1, 3, and 6.
How we tested the Energy Bra
- 6 months of four-times-weekly wear across yoga, pilates, walking, and moderate cardio
- Support test through 100 jumping jacks at month 1 and month 6
- 35 wash cycles, line-dried, with elastic and pad check
- Cup-fit comparison across 34DD frame
- Side-by-side comparison against Athleta Ultra High Support and Knix Catalyst
- Strappy-back stay-put test through full range of motion

Who should buy the Energy Bra?
Buy if:
- You wear a 32A to 38DDD and value cup-specific sizing
- Your activity is yoga, pilates, walking, or moderate cardio
- You want a strappy back that adds visual interest without sacrificing function
- You can rotate two bras to extend lifespan
Skip if:
- You run regularly and wear a C+ cup (Brooks Drift or Athleta Ultra is better)
- You want a maximum-support bra for high-impact activity
- You hate strappy backs for getting in and out
Cup-specific sizing: the real value
The Energy Bra runs in band sizes 32 to 38 with cup options A through DDD. That coverage is rare at this price tier. Most $40 to $60 sports bras still ship in S-M-L, which is fine for under a B cup and fails above. My 34DD fit perfectly out of the package and the cup did not bunch or gap. A friend in 36C reported the same.
Medium-impact support: appropriate for the category
In 100 jumping jacks at month 1 and month 6, my Energy Bra controlled bounce well for moderate activity but would not be the bra I would pick for a 5K run. That is by design. Lululemon classifies it as medium support and the construction matches the claim. For yoga, pilates, walking, and weight training, the support is enough. For running with anything above a B cup, look elsewhere.
Comfort: minimal pressure, smooth seams
The Luxtreme fabric is the same blend Lululemon uses across performance leggings. Against the skin it reads soft, the seams are flat, and the band does not dig at the ribs. After a 90-minute hot yoga class my bra came off with no red marks at the band or under the arm.
Pad performance: stays flat
The removable pads in the Energy Bra are thinner and more contoured than the foam squares in cheaper bras. After 35 wash cycles they have not bunched, curled, or shifted. The trade-off is that they are slightly tricky to reinsert after washing. Most users solve this by leaving them in.
Durability: 35 washes, no shape loss
The Luxtreme fabric holds its shape across at least 35 wash cycles. The strappy back elastic has not loosened. The band has not stretched out. Compared to the cheaper drop-ship style bras at $22, which lose support after 10 to 15 washes, the Energy is a clear durability win.
Should you buy the Energy Bra?
For medium-impact training in cup sizes A through DDD, yes. The Energy Bra is one of the most reliable options at $58 and the cup-specific sizing is rare at this price. For high-impact running with a C+ cup, the Brooks Drift or Athleta Ultra is the smarter spend. Skip generic drop-ship bras at this price; the durability gap shows up by month two.

Should you buy the Lululemon Energy Bra Medium Support?
The Energy Bra is one of the few mid-impact bras that uses real cup sizing instead of vague S-M-L. The Luxtreme fabric holds shape, the strappy back gives some range of motion, and the removable pads stay smooth across 30+ washes. Best for B to D cups doing yoga, pilates, walking, or moderate cardio. Not enough support for runners with C+ cups.
Frequently asked questions
Is the Lululemon Energy Bra worth $58 in 2026?+
Yes for B to D cups doing medium-impact activity. The cup-specific fit is the differentiator at this price, and the Luxtreme fabric holds shape across at least 35 washes. For high-impact running or larger cups, the Brooks Drift or SheFit Ultimate is a smarter spend.
Energy Bra vs Athleta Ultra High Support: which is better?+
Athleta Ultra has higher support and is built for running with C+ cups. Energy Bra is medium-impact and best for yoga, pilates, and moderate cardio. If you train under a B cup, either works.
How does the strappy back hold up?+
The straps are functional, not decorative. They distribute load across the shoulders and provide some range of motion. After 35 washes, the elastic in the straps has not loosened in our pair.
Should I size up or down in the Energy Bra?+
Order true to your cup size. If you are between band sizes, go down. The Luxtreme fabric has enough stretch to accommodate a slightly snug band, but a loose band loses support quickly.
