People often confuse "low impact" with "low intensity." When you train in a low-impact format, the only thing that decreases is the wear and tear on your joints; intensity of movement, speed, and muscular recruitment all remain high.
In challenging weather, it's important to be able to calibrate your workouts for success. For example, instead of a jump squat, do a regular squat. To keep the intensity, either deepen the range of motion or increase the frequency. You're still accessing the same muscle groups, and going faster or lower in the squat will keep the intensity up. Try a low-impact cardio workout like this one for a safe but effective Summer sweat session.
