We will often see events that'll run a multi part workout on a continuous clock in a single heat.
For example, you may have Workout 1 is a 2 part workout:
Part 1: 5 Min to establish a 1RM Snatch
1 minute transition into...
Part 2: 3 Min AMRAP
10 Thrusters
10 Pull-Ups
Simply create one workout as "Workout 1: Part A" and another workout as "Workout 1: Part B"
Set the relevant scoring parameters for each, in this example, Part 1 will be 'For Weight' and Part 2 will be "For Repetitions"
For both parts, you can replicate the same Heat and Schedule for consistency.
