Left is the start. Right is the finish. Match the shape, then add load.

How to handle weight
Intervals should leave you able to hit the same split on the last round. If round one is a sprint you cannot repeat, you started too hot. Bike / rower: watch watts or pace, not pride.
Usual programming
45–60s pulse raise.
Caution
Skill before chaos. Land quietly on jumps. On the bag, hands up before power. Burpees: step back if the low back complains. Stop a round if you go dizzy — sit, do not keep swinging.
Setup
Jump out, arms up, jump in, land quiet.
