It's so nice out, quite often I refuse to do my workouts indoors, we're stuck inside like 8 months out of the year here, let me enjoy these months!! This is a great workout that will definitely get the heart rate up; focus here is mainly lower body with some core, chest and shoulders thrown in. No equipment required! 
Perform each exercise for 45s for 4-6 rounds. Take 2-3 minutes rest between rounds

1. Hop overs 

Find a low bench place both hands down and hop side to side over the bench (or behind if it's too wide) Keep the landing light and and core braced as you push side to side. 

2. Mountain Climbers

From high plank position, drive knees up towards midsection, keep the hips level and core braced throughout. Legs are the only things moving, everything else remains stable. 

3. Step overs

One leg remains on bench, bring one leg down to the ground, press through the leg on the bench and then alternate to the other side. Essentially you're just performing a lateral step up, but the timing is quicker and you shift back and forth. 
Modification: Just perform step ups

4. High plank reach + push up 

Start holding onto the bench with arms outstretched, bring one arm at a time down to be underneath shoulder height and then perform a push up. Once back in the high plank position of the push up grad onto the bench one arm at a time again. 
Modification: From the knees

5. Box Jumps

Sink into hips feet shoulder width apart and drive up to softly land on the bench and step back down to perform again. 
Modification: Squats

6. Curtsy Lunges 

Grab your favourite doggo (or perform them just bodyweight) bring one leg behind the other sink into that hip, the front leg is the one you push up off of and alternate back and forth


7. Leg Lowers off bench 

Find a comfortable position so your sit bones are on the bench, keep the back nice and straight and neck neutral. Bend knees in towards chest and slowly lower them with control not using your low back. 
Modification: Lay flat on bench and lower one leg at a time down.
