How to progress this
Run this session as written for your first week. In week 2, add one rep per set on the first three main exercises. Week 3, add a set. That's progressive overload — the mechanism behind every result, at any session length. The app automates exactly this across a 4-week cycle, with a planned lighter week so you recover instead of stalling.
Why this session is built this way
Sample of trimester-aware selection (no supine, no prone, impact-free). The app applies these rules automatically after screening. The selection balances movement patterns (squat, hinge, push, pull, core) so nothing gets overworked — the same rule set the app engine validates on every plan it generates, including volume caps per muscle per week.

FAQ
Is a 20-minute second-trimester strength session enough?
For moving better and feeling looser, yes — when every minute is structured. This session flows through progressive mobility and breath work sized to the time you have. Sample of trimester-aware selection (no supine, no prone, impact-free). The app applies these rules automatically after screening.
What if an exercise doesn't work for me?
Every exercise below lists safe, same-pattern substitutions — pick one and the session still balances. In the app, the engine applies your own constraints (knees, shoulders, pregnancy stage, noisy-apartment mode) automatically when it builds YOUR plan.
How do I make it harder or easier?
Easier: drop a set, rest 15–30s longer, use the first substitution listed. Harder: add a set to the first three main exercises, slow the lowering phase to 3 seconds, or shorten rests. The app versions this progression across a full 4-week cycle.
