The same rule applies as with lifting:
Type 1A are all about intensity. They should have the shortest but most intense workouts. They also should avoid excessive adrenaline production (which can go against the short and intense cardio bouts). The best options for them are heavy loaded carries for 20-30 meters (farmer’s walk, Zercher carries, prowler pushing) with ample rest between sets (75-90 sec). They can also do reasonably well on on/off intervals … sprint 30-45 sec / complete rest 75-90 sec
Type 1B are all about explosiveness. Their cardio work should also be short and intense like 1A BUT the pace and speed can both be faster. They do great on regular HIIT, sprints, prowler sprints, assault bike sprints, rower sprints, etc.
With type 2A everything works, but nothing works for long. They also get mentally fatigue when they do the same thing for too long. They can do all types of cardio mentioned here but they would either change the type every day or stick to one type for around 2 weeks before changing.
With 2Bs I like to use a mix of lighter loaded carries (not focusing on speed) for a duration of round 45-70 sec per set and steady sttate cardio. 2Bs are those who normally have the best lactic acid tolerance. Using longer loaded carriy sets or medleys can maximize lactic acids which in itself can help fat loss. They can either do 2 days of loaded carries and 2 days of steady state cardio, or mix both on every session in smaller amounts.
Type 3 are designed for endurance so longer duration cardio sessions will be their best option
