Is cardio or strength training better for losing fat and keeping muscle?

Strength training does more for your muscle, and doing both did best of all. In that same meta-analysis, strength training on top of eating less prevented about 61% of the lean mass loss, cardio about 26%, and the two together about 66% (Deller et al., 2026). I'd keep both, and do strength first on days you do both.

Will strength training make me bulky?

Very unlikely, especially while you're eating less. In the biggest meta-analysis on protein and strength training, people who were eating enough gained about 1.1 kg (around 2.4 pounds) of lean mass over roughly 13 weeks on average (Morton et al., 2018), and muscle comes on slower than that in a deficit.

Can you lose fat and keep muscle with 30-minute workouts?

Yes. Three short full-body sessions a week covers the WHO's recommendation of strength training on 2 or more days a week (WHO guidelines on physical activity, 2020). Talala, the AI personal trainer app, plans each workout around the time you've got, from about 20 to 60 minutes, and the equipment in front of you, whether that's a full gym, a hotel gym or dumbbells at home.

How does Talala help if you want to lose fat and keep muscle?

Talala plans every strength session for you, and your coach talks you through every set. Your coach builds the plan from your goals, schedule and gym, stays with you every step of the way to keep you motivated, and you can ask your coach anything mid-workout, like what to do if a machine's taken. It's free right now on iPhone, with Android coming soon. ---

I was following Youtube and Ladder workouts for the longest time, they were good but they never felt personalized to me. Until Talala came along. I love that I get to visualize and understand what's actually getting stronger. And every time I improve, I'm so freaking proud of myself!! Love this app so much

Jen

I was trying to save money so I had to stop going to classes and seeing my trainer. THANK GOD I found the Talala app. It's truly a game-changer. I've now been able to keep up with my gym sessions. I love the posture tips Talala gives me. I love that it just lays everything out for me. This app is a steal!

Angela

I love visualizing just how my body is improving over time. Not only that, I love the cardio session recaps, so I can see how long I was in zone 4 vs zone 2 for. Really love this app!

Matt

Honestly... this is better than my last trainer. I had no clue what was going on in my body or my workouts. I was just following whatever they told me. But now with Talala, I feel like everything's in my control. I LOVE that this app does longevity workouts because I want to live long to see my kids and future grandkids grow up!

Lisa

I'm someone who travels almost every week for work. Meaning I get a different gym every time. I love that I'm able to still train my muscles based on whatever equipment is available. Can't recommend this app enough!

Questions

Strength train 2 to 3 times a week, eat enough protein, and eat only a little less than your body needs. In a 2026 meta-analysis of 34 trials, people who added strength training to eating less held on to most of the lean mass they'd otherwise have lost (Deller et al., 2026). The details on protein and how small to keep the deficit are in how to keep muscle in a calorie deficit.
